U.K. threat level raised to critical after subway bomb
A homemade bomb planted in a rush-hour subway car injured 29 people in London on Friday, sparking a huge manhunt for the perpetrators of what police said was the fourth terrorist attack in the British capital this year.
Prime Minister Theresa May said the device “was intended to cause significant harm,” but to the relief of authorities and Londoners, the bomb — hidden in a plastic bucket inside a supermarket freezer bag — only partially exploded, sparing the city much worse carnage.
“I would say this was a failed high-explosive device,” Chris Hunter, a former British army bomb expert, said of the blast, which caused no serious injuries.
Late Friday The Islamic State group claimed the London subway explosion was carried out by an affiliated unit.
The bomb went off around 8:20 a.m. as the train, carrying commuters from the suburbs — including many school children — was at Parsons Green station in the southwest of the city.
Witness Chris Wildish told Sky News that he saw “out of the corner of my eye, a massive flash of flames that went up the side of the train,” followed by “an acrid chemical smell.” Commuter Lauren Hubbard said she was on the train when she heard a loud bang.
“I looked around and this wall of fire was just coming toward us,” Hubbard said. She said her instinct was “just run,” and she fled the above-ground station with her boyfriend. Chaos ensued as hundreds of people, some of them suffering burns, poured from the train, which can hold up to 800 people.
“I ended up squashed on the staircase. People were falling over, people fainting, crying. There were little kids clinging onto the back of me,” said another commuter, Ryan Barnett. Passenger Luke Walmsley said it was “like every man for himself to get down the stairs.”
“People were just pushing,” he added. “There were nannies or mums asking where their children were.”
Police and health officials said 29 people were treated in London hospitals, most of them for flash burns. None of the injuries were serious or lifethreatening, the emergency services said.
Trains were suspended along a stretch of the Underground’s District Line, and several homes were evacuated as police set up a 50-meter (150-foot) cordon around the scene while they secured the device and launched a search for those who planted it.
The Metropolitan Police said hundreds of detectives, along with agents of the domestic spy agency MI5, were looking at surveillance camera footage, carrying out forensic work and speaking to witnesses. Among questions they were rushing to answer: What was the device made from, and was it meant to go off when it did, in a leafy, affluent part of the city far from London’s top tourist sites?
British media reported that the bomb included a timer. Lewis Herrington, a terrorism expert at Loughborough University, said that would set it apart from suicide attacks like those on the London subway in 2005 or at Manchester Arena in May, in which the attackers “all wanted to die.”
Photos taken inside the train showed a white plastic bucket inside a foil-lined shopping bag, with flames and what appeared to be wires emerging from the top.
Terrorism analyst Magnus Ranstorp of the Swedish Defence University said that from the photos it appeared the bomb did not fully detonate, as much of the device and its casing remained intact.
“They were really lucky with this one, it could have really become much worse,” he said.
