Armed police close to Parsons Green station in west London after an explosion on a packed London Underground train

An explosion and fire aboard a crowded London subway auto injured several passengers and interrupted service early Friday, in what police say is a terror-related attack. As a manhunt takes place across the capital, authorities have tightened security on all transport hubs, The New York Times reports.

The cause of the blast was an "improvised device" that failed to fully explode, police said.

Others were trampled and suffered crush injuries in the rush to escape the packed carriage, which was the last in the train.

"The Met's Counter Terrorism Command is investigating after the incident at #Parsons Green tube station is declared a terrorist incident", police wrote on Twitter.

The station was closed, as well as an entire section of the District Line, and police urged people to stay away from the area.

Pictures taken at the scene showed a white bucket in flames containing a freezer bag on the floor of one train carriage.

Several passengers received burns and dozens hurried to leave the train and get out of harm's way.


Police report several people suffered severe burns after flames swept through the vehicle, but their injuries did not appear to be life-threatening.

Prime Minister Theresa May tweeted, "My thoughts are with those injured at Parsons Green and emergency services who are responding bravely to this terrorist incident".

London Ambulance Service Operations assistant director Natasha Wills said: "We have sent a number of resources to the scene, including ambulance crews, officers and our Hazardous Area Response Team".

Police said they were aware of reports on social media and said they would release facts regarding the incident once they could be sure of their accuracy.

Islamic State claimed responsibility as well as for a June attack near London Bridge which left eight dead. She said the UK's terror threat level would remain at severe - the second highest - but would be under review.

US President Donald Trump denounced the attack by "sick and demented people who were in the sights of Scotland Yard".
