The Islamic State group on Friday claimed responsibility for a bomb attack on a packed London Underground train the same day that injured at least 29 people.
“The bombing on a metro in London was carried out by a detachment of the Islamic State” group, it said in a statement published by its Amaq propaganda agency.
Police said was Britain’s fifth terrorism incident this year, but apparently failed to fully explode.
British police said they have identified the attacker.
Passengers on board a train heading into the capital fled in panic as the fire erupted at Parsons Green underground station in West London at 8.20 a.m.
Some suffered burns while others were injured in a stampede to escape. The National Health Service said 22 people had been taken to London hospitals, most believed to be suffering flash burns. None were thought to be in a serious condition, the ambulance service said.
