Four people were killed and about 40 others were wounded Wednesday after a terrorist plowed his car into pedestrians on Westminster Bridge in London and then stabbed a policeman near the parliament building. The terrorist was shot at the scene and later succumbed to his injuries in the hospital. Three of the fatalities in what police called a "marauding terrorist attack" were among those hit by the attacker's car as it sped across Westminster Bridge before crashing into railings just outside parliament. The dead police officer was identified as Keith Palmer, 48, with 15 years of service. British police believe the attack was linked to Islamic terrorism and are checking whether the lone attacker was supported by anyone else, the country's defense secretary said on Thursday. "The police are investigating this man, his associates, where he came from," Michael Fallon told BBC Radio. "[They are] checking urgently whether other people were involved in this. Their working assumption is that this is linked to Islamic terrorism." On Thursday, the police said that they had arrested seven people across the country. Mark Rowley, Britain's most senior counter-terrorism officer, said that police had searched six addresses in London, in Birmingham and elsewhere in the country in search of culprits. Prime Minister Theresa May condemned the attack, which is likely to be remembered for the ease in which terror can strike at the heart of Britain, as "sick and depraved." "The location of this attack was no accident," she said in a statement outside her 10 Downing Street office late in the evening. "The terrorist chose to strike at the heart of our capital city, where people of all nationalities, religions and cultures come together to celebrate the values of liberty, democracy and freedom of speech." Any attempt to defeat those values through violence was "doomed to failure," May said. Rowley told reporters the attack started when a car was driven over Westminster Bridge, indiscriminately hitting and injuring civilians and police officers. "A car then crashed near to parliament and at least one man, armed with a knife, continued the attack and tried to enter parliament," Rowley said. He said the police's "fast-paced investigation" was working on the assumption that the attack was "Islamist-related terrorism." Police believed they knew the identity of the attacker but would not provide details at this stage, he said. It was the deadliest attack in London since four British Islamists killed 52 commuters and themselves in suicide bombings on the city's transport system in July 2005, in London's worst peacetime attack. The attack took place on the first anniversary of attacks by Islamist terrorists that killed 32 people in Brussels. A Reuters photographer saw at least a dozen people wounded on the bridge. His photographs showed people lying on the ground, some of them bleeding heavily and one under a bus. A woman was pulled alive, but with serious injuries, from the Thames, the Port of London Authority said. The circumstances of her fall into the river were unknown. Three French schoolchildren aged 15 or 16 were among those wounded in the attack, French officials said. Several members of parliament and senior officials were caught up in the chaos. Tobias Ellwood, a junior Foreign Office minister, was pictured attempting to resuscitate a man lying unconscious, reported to be the stabbed policeman. London Mayor Sadiq Khan said there would be additional police officers on the city streets to keep Londoners and visitors safe. "We stand together in the face of those who seek to harm us and destroy our way of life. We always have, and we always will. Londoners will never be cowed by terrorism," he said. Parliament's lower House of Commons, which was in session at the time, was suspended and lawmakers were asked to stay inside the building for several hours. May said parliament would convene as normal on Thursday in a sign that the attack would not disrupt life in the capital. However, a visit by Queen Elizabeth to officially open the new headquarters of London's police force, which had been planned for Thursday, was postponed "in light of today's events," Buckingham Palace said. Eyewitnesses described scenes of panic during the attack. "I just saw a car go out of control and just go into pedestrians on the bridge," said Bernadette Kerrigan, who had been on a tour bus on the bridge, in an interview with Sky News. "As we were going across the bridge, we saw people lying on the floor, they were obviously injured. I saw about 10 people maybe. And then the emergency services started to arrive. Everyone was just running everywhere." Former Polish Foreign Minister Radoslaw Sikorski, who witnessed the attack from a taxi as he crossed the bridge, said he saw five victims and made a video of the scene. "I heard something that sounded like a small car crash. Then I looked out of the window and saw that there was one person lying on the asphalt," he said. "I did not see the face of the person lying on the asphalt, but the person was not moving
not showing any signs of life. One of the men I saw, his head was bleeding very badly. But the person I filmed -- no, that person was not showing any signs of life." Journalist Quentin Letts of the Daily Mail newspaper told LBC radio that he had witnessed the stabbing of the policeman and the shooting of the assailant from his office in the parliament building. "He [the assailant] ran in through the open gates. ... He set about one of the policemen with what looked like a stick," Letts said. "The policeman fell over on the ground and it was quite horrible to watch and then having done that, he disengaged and ran toward the House of Commons entrance used by MPs and got about 20 yards or so when two plain-clothed guys with guns shot him." In Edinburgh, the Scottish parliament suspended a planned debate and vote on independence as the news from London came in. Britain is on its second-highest alert level of "severe" meaning an attack by terrorists is considered highly likely.
