Several boats have sunk on a lake in the US state of Texas during a parade to support President Donald Trump in November's election, officials say.
Authorities say the choppy water was likely caused by the large number of vessels moving closely together on Lake Travis, near the state capital, Austin.
Images showed boats with Trump campaign flags manoeuvring at close quarters.
Media say people had to be rescued from the water, but there were no immediate reports of injuries.
The event, called Lake Travis Trump Boat Parade, was organised on Facebook, and more than 2,600 people marked themselves as having attended it.
An investigation has been launched and there is no evidence of any intentional act, Travis County Sheriff's Office spokeswoman Kristen Dark said.
"We responded to multiple calls of boats in distress, several of them sank," she said. "We had an exceptional number of boats on the lake today... When they all started moving at the same time, it generated significant waves."
The incident happened around 12:00 (17:00 GMT) on Saturday, Labor Day weekend in the US. The event page said boats were asked to drive at 10mph (16km/h).
Paul Yura, from the National Weather Service in Austin/San Antonio, told the Associated Press that there were no storms in the area at the time of the parade.
Rescuers in Beirut have found "no sign of life" in the rubble of a building destroyed in last month's massive port explosion, dashing hopes that someone could be rescued alive.
A sensor machine detected possible signs of life on Thursday, but after clearing 95% of the rubble workers have not found the source of the reading.
About 50 volunteers, including a team from Chile, have been at the scene.
The blast killed about 190 people and left thousands of others injured.
Crowds gathered at the building located between the residential districts of Gemmayze and Mar Mikhael, hoping for a miracle.
What's the latest with the search?
A team of rescuers from Chile were walking through the area on Wednesday night when their sniffer dog gave a sign that there was a person inside.
When they returned on Thursday, the dog again gave the same signal. Specialist sensor equipment then detected a pulsing signal in the area.
Breathing was detected under the rubble at a depth of 3m (9.8ft).
They continued to remove the rubble on Saturday, clearing much of it by hand. However they have still not located the source of the sensor reading.
In a news conference on Saturday, Francisco Lermanta, head of volunteer rescue group Topos Chile, said: "Technically speaking, there are no signs of life."
He told reporters that signs of life recorded over the past two days were the breaths of volunteers working inside the building.
Rescuers say there are no signs of life in the rubble of a building they have been searching following a huge explosion in Beirut last month.
The search began on Thursday afternoon after a sniffer dog detected something in rubble in the Gemmayze area of the Lebanese capital.
Audio detection equipment had detected a pulse of 18 to 19 beats per minute, sparking hope there might be life.

However, on Friday morning, it was reported the signal had decreased to seven.
Rescuers had said it suggested someone could be alive or in a coma - or it could just be an object emitting a signal.

Around 50 rescue workers and volunteers, including a specialist team from Chile, continued to dig through the rubble for a third day on Saturday.
They said they would carry on despite there being a small chance of finding a survivor, and had narrowed their search.

Thermal imaging and scanning equipment was also being used as rescue teams removed debris, digging with their hands and shovels - careful to protect any survivors.

"Always in search operations like this, you can neither lose hope nor absolutely say there is hope," said George Abou Moussa, director of operations in Lebanon's civil defence.
The huge blast on 4 August killed about 190 people, injured 6,000 more and devastated whole neighborhoods.

Almost 3,000 tonnes of ammonium nitrate set off the explosion that tore through Beirut - considered one of the biggest non-nuclear explosions ever recorded.
Ceremonies were held on Friday to mark a month since the explosion tore into a city already reeling from a crippling economic crisis.

The ruined building where the search was continuing is located between the residential districts of Gemmayze and Mar Mikhael, which are among the hardest hit areas by the blast and home to many old buildings that crumbled as the shockwave ripped through.
The search was briefly halted on Thursday due to concerns about the unstable structure.
The area was inspected by the army following fears a wall might collapse and two cranes were bought so it could be safely removed.
Beirut explosion: One month on
Days after the blast, more than 20 containers of ammonium nitrate were found at the port and moved to safe locations.
On Thursday, the army said it had found another 4.35 tonnes of the chemical compound in four containers near the port, which are being investigated.
A total of 25 people have being detained over the explosion, the majority either port or customs officials.
Paul Rieckhoff of the Iraq & Afghanistan Veterans of America, tweeted: "Who is really surprised by this?"
A small group of protesters waved placards at the president's motorcade on Saturday near the Trump National Golf Club in Virginia.
Mr Trump has often staked a claim to strong support among the military, and last year Pew Research Center found that veterans were generally supportive of him as commander-in-chief, with 57% in favour. Three-fifths of the veterans identified as Republican, the research found.
What is Trump reported to have said?
According to The Atlantic, when Mr Trump cancelled a visit to the Aisne-Marne American Cemetery outside Paris in November 2018, 100 years after the end of World War One, he said it was "filled with losers".
Four sources told the magazine he had rejected the idea of visiting because the rain would dishevel his hair, and he did not believe it important to honour America's war dead.
During the same trip, the president also allegedly referred to 1,800 US soldiers who died at Belleau Wood as "suckers". The battle helped to prevent a German advance on Paris during World War One and is venerated by the US Marine Corps.
The US Navy also said it cancelled the trip to the cemetery because of rain in response to a request under the Freedom of Information Act from Buzzfeed reporter Jason Leopold.
How did Trump react?
Without referring to Jeffrey Goldberg, the author of the Atlantic report, by name, he tweeted on Saturday: "You work so hard for the military, from completely rebuilding a depleted mess that was left by OBiden [the previous presidential administration when Joe Biden was vice-president to Barack Obama], to fixing a broken V.A. and fighting for large scale military pay raises, and then a slimeball reporter, maybe working with disgruntled people, makes up such a horrible charge.."
"This reminds me of the Dirty Dossier [the Steele dossier which alleged collusion with Russia], which was pushed hard by John McCain, & then with a thud turned out to be a total fraud. So many other scams also. The Radical Far Left is VICIOUS, they will do or say anything to win. But they won't, we will WIN, & have four great years!"
Mr Trump went on to attack another journalist, Jennifer Griffin of Fox News, normally one of the president's favourite news outlets.
If elected, he said, he would "ensure that our American heroes know that I will have their back and honor their sacrifice. Always."
Democratic Senator Tammy Duckworth, a veteran who lost both legs while serving in Iraq, said President Trump "liked to use the US military for his own ego".
He said: "When Donald Trump calls anyone who places their lives in service of others a loser, we understand Trump's soul."
Where do Trump and the US military stand?
There have been previous spats and controversies.

Mr Trump caused outrage by saying the late Senator John McCain, a prisoner of war in Vietnam, was not a "war hero" saying: "I like people who weren't captured."
The president has never served in uniform. He received five deferments from a military draft during the Vietnam War - four for academic reasons and one for bone spurs, a calcium build-up in the heels.
Donald Trump has failed to join other world leaders in condemning Russia for an alleged Novichok poison attack on opposition leader Alexei Navalny.
The US president told reporters on Friday that "it's tragic. It's terrible, it shouldn't happen. We haven't had any proof yet, but I will take a look", before asking why they were focused on Russia, rather than China.
He said his administration will "have to look at it very seriously, if it's the case".
However, Mr Trump later said he would not be happy if Russia did poison Mr Navalny, "and that seems to be the case".
He fell ill on a flight to Moscow and has been in an induced coma for more than a week after being flown to Germany, where he is being treated at a hospital in Berlin.
Supporters believe the pro-democracy campaigner was poisoned at an airport in Siberia while waiting for the flight.
More from Alexei Navalny
Not for the first time, Mr Trump's stance is in sharp contrast to that of many of Washington's traditional allies.
Germany has said Mr Navalny was poisoned with a Soviet-style Novichok nerve agent - the same substance used against Sergei and Yulia Skripal in Salisbury in March 2018 - and is demanding the perpetrators be held to account.

Boris Johnson said the Russian government "must now explain what happened to Mr Navalny", adding that it was "outrageous that a chemical weapon was used".
NATO secretary-general Jens Stoltenberg condemned the "appalling assassination attempt" on Mr Navalny.
He said: "There is proof beyond doubt that Mr Navalny was poisoned using a military-grade nerve agent from the Novichok group. The use of such a weapon is horrific."
Even the US State Department went further than the president, expressing grave concern about the matter.

In a meeting in Washington, Deputy Secretary of State Stephen Biegun told Russian Ambassador Anatoly Antonov that Moscow's use of this chemical weapon would be a clear violation of its obligations under the Chemical Weapons Convention.
Spokeswoman Morgan Ortagus said in a statement: "The Deputy Secretary urged Russia to cooperate fully with the international community's investigation into this attack."
Russia has denied any involvement in the affair, has not opened a criminal investigation and said there is no evidence yet of a crime.
Mr Navalny is the most popular and prominent opponent of President Vladimir Putin, and Germany's confirmation that he was poisoned has raised the possibility of further Western sanctions against Moscow.
Rescue workers may have found another 'heartbeat' under the rubble left when an explosion rocked the Port of Beirut last month - raising fresh hopes a buried survivor might still be alive after the blast.
Search operations began on Thursday afternoon after a sniffer dog belonging to a Chilean search and rescue team detected something as the team was going through the neighbourhood of Gemmayzeh and rushed towards the rubble.
On Thursday, the team used audio detection equipment for signals or heartbeat, and detected what could be a pulse of 18 to 19 beats per minute.
Last night, a month after the blast tore through Beirut, unconfirmed social media reports suggest the Chilean search team have now found an additional heartbeat under the debris.

'The #ToposChile team just ran a test and breathing was confirmed. Digging into the rubble continues. Some new reports are that it may be two children-most likely flower vendors,' Maya Yahya, the director of Carnegie Middle East, wrote on Twitter, citing a TV report from AlJadeed News.
Salman Andary, of Sky News, wrote in Arabic on Twitter that the rescue team's sensors had detected a heartbeat again under the blast wreckage.
'Chilean team finished the process and were able to, once again, find a person's breath under the rubble,' Andary said, adding that the process took 40 minutes and the 'heartbeat' was scanned several times.
Rescue workers continued to dig through the rubble of a Beirut building for a third day this morning.
About 50 rescue workers and volunteers, including a specialist team from Chile, had yet to locate anyone after sensors on Thursday detected the signs of breathing and heat.

Rescuers search at the site of a collapsed building after getting signals there may be a survivor under the rubble, in Beirut, Lebanon this morning. A pulsing signal was detected Thursday from under the debris of a Beirut building that collapsed during the horrific port explosion in the Lebanese capital last month, raising hopes there may be a survivor still buried there
Fires were still burning at the destroyed port following the blast as the full extent of the devastation - in a country that was already in the midst of an economic crisis - was laid bare
They said they would continue while there was a small chance of finding a survivor, and had narrowed their search.
'Always in search operations like this, you can neither lose hope nor absolutely say there is hope,' George Abou Moussa, director of operations in Lebanon's civil defence, told Reuters.
The Aug. 4 blast killed about 190 people, injured 6,000 more and devastated whole neighborhoods. The authorities held ceremonies on Friday to mark a month since the explosion tore into a city already reeling from a crippling economic crisis.
Rescue efforts dominated local and social media, as the Lebanese were transfixed, desperate for some good news.

The ruined building where the search was continuing lies between the residential districts of Gemmayze and Mar Mikhael, among the hardest hit areas by the blast and home to many old buildings that crumbled as the shockwave ripped through.
Work was slow, rescue workers said, as the badly damaged building was at risk of collapse.
'The building is really crumbling, it's scary and there's a lot of danger to the team,' Abou Moussa said.
Workers were using shovels and their hands to dig, while mechanical diggers and a crane lifted heavy debris.
Emmanuel Durand, a French civil engineer who was training local university students, volunteered his services and was working with the rescuers to monitor the structure.
Scanning the building with high-precision lasers, Durand said his team had so far not found any signs of movement.
There has been outrage that so much hazardous material was stored unsafely in a warehouse in the city's port, close to many residential areas.
The Lebanese government's resignation shortly afterwards failed to pacify protesters, who clashed with police in the city for several nights.
One month on, seven people are still missing, according to Lebanese officials.
What's happening with the search?
Search efforts got under way after a rescue team from Chile said it had detected possible signs of life under a destroyed building located between the residential districts of Gemmayze and Mar Mikhael.
The rescuers were walking through the area on Wednesday night when their sniffer dog - trained to find bodies - gave a sign that there was a person inside. When they returned on Thursday, the dog went to the same place and gave the same sign. Specialist sensor equipment then detected a pulsing signal in the area.
The head of the Chilean rescue team, Francisco Lermanda, told reporters on Friday that slow breathing had been detected under the rubble at a depth of 3m (9.8ft).
Rescuers dug three tunnels to try to reach the spot where the pulse was detected, he said.
But, he added, it was too soon to know if anyone was "alive or dead" beneath the debris.
Earlier on Friday, rescue co-ordinator Nicholas Saade told the AFP news agency that the pulse had slowed significantly since the previous day. Reporters at the scene said the most recent test detected no signals at all.
Crowds have been gathering to watch the search efforts, hoping for a miracle.
"Search operations have been going on since the day before yesterday but the chances are very low," the civil defence agency's operations director, George Abou Moussa, told AFP.
