China Tiananmen Square car blaze kills five people
Chinese state media have said at least five people died and 38 others were injured after a vehicle crashed in Tiananmen Square in Beijing.
Three of those killed were inside the car and the other two were bystanders.
The square was evacuated and quickly reopened after the vehicle went into the crowd in front of the Tiananmen rostrum at midday.
Images posted online showed a vehicle in flames, amid barricades. There has been no explanation for the crash.
Other pictures on social media showed a column of smoke rising from the scene of the crash.
Three people inside the vehicle died, Beijing police said on its official microblog account, adding that one female tourist from the Philippines and a male tourist from Guangdong province had also died.
Senior leaders from both the central government and the local authorities in Beijing and the Ministry of Public Security have visited the scene, it said.
An investigation is under way and the injured have been taken to hospital, Beijing police said.
Was it an accident or some sort of political protest?
That is the question that hangs in the air following Monday's deadly vehicle accident at the entrance to the Forbidden City, one of China's most popular tourist sites. The entrance to the Forbidden City borders the northern edge of Tiananmen Square, the location of 1989's crackdown on pro-democracy campaigners and an ongoing flashpoint for disgruntled citizens.
Users of weibo, China's version of Twitter, were quick to question the location of the crash. "Tiananmen is a political landmark… Fires in other places are local news but this is different," wrote one poster, Chaijuncat.
According to some, Tiananmen Square is the most heavily policed public area in the world. Monday's episode lends credence to that idea. Minutes after the incident, police evacuated the square. They were also quick to put up screens to shield the location where the jeep crashed into the bridge, which lies below the iconic portrait of Communist Party founder Mao Zedong.
Our BBC crew attempted to record video of the incident's location as we drove through the square and the police quickly forced us to pull over to the side of the road. We were detained for approximately 20 minutes inside one section of the Forbidden City while the police checked our journalist credentials before letting us go.
Minutes later, when we drove past the area again, it had returned to its uneasy status quo. The area had been cleaned. Crowds of tourists arriving at that moment would not have known that anything abnormal had taken place. Weibo had also been wiped clean. Questioning comments, like the one posted by Chaijuncat, had disappeared.
Tiananmen Square was the scene of the 1989 pro-democracy protests which were ended by a military crackdown.
The site is generally kept under very tight security both because of its proximity to key political institutions and so that is does not serve as a hub for protesters and petitioners.
Incidents do occur, nonetheless. In 2011, a man set himself on fire at Tiananmen Square following what officials said was a legal dispute, close to the square's portrait of Chairman Mao.
Two years before that, three people set themselves on fire in a car at a busy intersection near Tiananmen Square over what the authorities called personal grievances.
In 2000, several members of the banned Falun Gong spiritual movement were arrested for protesting at the square.
Fire extinguishers are kept at the site, and have been used when protesters set themselves on fire.'Bursting into flames'
Monday's incident took place at the north end of Tiananmen Square, near an entrance to the Forbidden City.
"A driver and two passengers were killed after a jeep crashed into a crowd of people and caught fire," Xinhua news agency said.
Citing police and emergency officials, it said police officers were among those injured by the jeep, "which crashed into a guardrail of Jinshui Bridge on the moat of the Forbidden City before bursting into flames at 12:05 pm".
One unnamed eyewitness told AFP news agency: "I saw a car turn a bend and suddenly it was driving on the pavement, it happened fast but looked like it knocked people over."
"I heard an explosion and saw fire. The scene was very frightening," he added. "There were paramilitary police who told people to get back into their cars and stop taking pictures."
In a microblog post on its verified Sina Weibo account, the Beijing police said that "the injured people were all sent to a nearby hospital".
"Police at the site immediately launched rescue efforts, and the fire was quickly extinguished... the situation is currently being investigated further," the police added.
A subway station close to the square was temporarily closed at the request of police, Beijing transport authorities said. Police also closed the road near the crash.
News of the incident first appeared on social media from those who were at the scene, but it appeared that some pictures were being quickly removed.
A BBC team that went to the site to gather footage said that they were detained for around 20 minutes before being released.
AFP news agency said that two of its reporters were also held close to the square, with images deleted from their cameras.
Chinese Foreign Ministry spokeswoman Hua Chunying, when asked whether the government believed the incident was a terror attack, said that she did not know the specifics of the case and declined further comment.
