A house exploded as police were investigating reports of gunshots being fired from the property by a man.
Footage of the blast in the US showed a huge fireball shoot up into the air as the entire home went up in flames and collapsed, spraying debris all around.
Witnesses said the explosion shook nearby buildings and that they could hear it from miles away.
Officers had gone to the address in Arlington, Virginia, at about 4.45pm on Monday after neighbours said they heard the sound of a weapon being fired.

They later determined the shots came from a flare gun, Arlington County police spokesperson Ashley Savage told reporters.
As officers tried to serve a search warrant at the home, “the suspect inside the residence discharged several rounds”, she said.
“The house subsequently exploded.”

It happened at around 8.25pm as officers were trying to make contact with the person inside – who has not been named by police.
Officials have not been able to go into the home and could not confirm whether there were any deaths. The suspect was inside when the explosion occurred, Ms Savage said.
“At this point, we’re only aware of one individual who was inside the home,” she added.
Some police officers suffered minor injuries and no one needed to be taken to hospital.
Carla Rodriguez, of South Arlington, said she could hear the explosion more than two miles away.
Bob Maynes thought maybe a tree had fallen on his house when he heard the explosion.
“I was sitting in my living room watching television and the whole house shook,” he said.
“It wasn’t an earthquake kind of tremor, but the whole house shook.”
The cause of the blast is being investigated, Arlington Fire Department officials said.
FBI agents and federal fire investigators are at the scene and assisting in the investigation, the Bureau of Alcohol, Tobacco, Firearms and Explosives said.
Donald Trump has filed a defamation lawsuit against the BBC, alleging the corporation’s Panorama documentary portrayed him in a “false, defamatory, deceptive, disparaging, inflammatory, and malicious” manner.
The complaint relates to the broadcaster’s editing of a speech he made in 2021 on the day his supporters overran the Capitol building.
Clips were spliced together from sections of the US president‘s speech on January 6 2021 to make it appear he told supporters he was going to walk to the US Capitol with them to “fight like hell”.
It aired in the documentary Trump: A Second Chance?, which was broadcast by the BBC the week before last year’s US election.
The US president is seeking damages of no less than $5bn (£3.7bn).
He has also sued for $5bn for alleged violation of a trade practices law. Both lawsuits have been filed in Florida.

BBC crisis: How did it happen?
‘They put words in my mouth’
Speaking in the Oval Office earlier on Monday, he said: “In a little while, you’ll be seeing I’m suing the BBC for putting words in my mouth.
“Literally, they put words in my mouth. They had me saying things that I never said coming out.”
The scandal erupted earlier this year after a leaked memo highlighted concerns over the way the clips were edited.
After the leak, BBC chair Samir Shah apologised on behalf of the broadcaster over an “error of judgement” and accepted the editing of the 2024 documentary gave “the impression of a direct call for violent action”.
The fallout from the saga led to the resignation of both the BBC director-general Tim Davie and the head of news Deborah Turness.
Earlier, BBC News reported the broadcaster had set out five main arguments in a letter to Mr Trump’s legal team as to why it did not believe there was a basis for a defamation claim.
In November, the BBC officially apologised to the president, adding that it was an “error of judgement” and saying the programme will “not be broadcast again in this form on any BBC platforms”.
A spokesperson said “the BBC sincerely regrets the manner in which the video clip was edited,” but they also added that “we strongly disagree there is a basis for a defamation claim”.
Four people have been charged with plotting New Year’s Eve bomb attacks in California.
Federal authorities in the US said the four are allegedly part of an extremist group which is suspected of planning the attacks in southern California.
The plot consisted of planting explosive devices at five locations targeting two US companies at midnight on New Year’s Eve in the Los Angeles area.
The suspects were arrested last week in Lucerne Valley, a desert city east of Los Angeles.

They are said to be members of an offshoot of a pro-Palestinian, anti-government and anti-capitalist group dubbed the Turtle Island Liberation Front, the complaint said.
As well as the alleged plan against the two companies, the group also planned to target Immigration and Customs Enforcement (ICE) agents and vehicles, attorney general Pam Bondi said.
The four defendants named in the complaint are Audrey Illeene Carroll, Zachary Aaron Page, Dante Gaffield, and Tina Lai.
All four are from the Los Angeles area, according to first assistant US attorney Bill Essayli.
The alleged plot
According to a sworn statement by the complaint, Carroll showed an eight-page handwritten document to a paid confidential source in November, which described a bomb plot.
The document was titled “Operation Midnight”.
Essayli said one of the suspects created a detailed plan that “included step-by-step instructions to build IEDs (improvised explosive device)… and listed multiple targets across Orange County and Los Angeles.”

Carroll and Page are then alleged to have recruited the other two defendants to help them carry out the plan which included acquiring bomb-making materials before constructing and performing test detonations.
Under the plan, the defendants would supposedly have travelled to a remote location in the Mojave Desert on the 12 December to construct and detonate their test explosive devices, the sworn statement alleges.
Evidence photos included in the court documents show a desert campsite with what investigators said were bomb-making materials strewn across plastic folding tables.
The FBI said agents intervened before the defendants could complete their work to assemble a functional explosive device.
