A member of Parliament, who spoke on condition of anonymity because, she said, “talking to the press at the moment would be frowned upon,” told Haaretz she and her colleagues were stuck in their offices as the lockdown of Westminster continued after an assailant was shot outside the building following a stabbing and car attack.
“We have been told not to leave where we are,” she said. “We are all just sitting at our desks, trying to figure out what’s happening – and watching live TV like everyone else.”
“Initially we heard there was a shooting. But now there was just an announcement on the loudspeaker saying there is concern about further incidents,” said the MP. "All those in the Parliament building," she continued, "were told that all the members and Ministers were safe.”
The incident is currently being treated as an act of terrorism.
Lawmaker Adam Holloway told the AP he saw people running and immediately ran into his offices in Parliament to be with his staff. "A lot of us are locked in with our staff at the moment," he said.
Witness Rick Longley told the Press Association that he saw a man stab a policeman outside Britain's Parliament.
"We were just walking up to the station and there was a loud bang and a guy, someone, crashed a car and took some pedestrians out," he said.
"They were just laying there and then the whole crowd just surged around the corner by the gates just opposite Big Ben.
"A guy came past my right shoulder with a big knife and just started plunging it into the policeman.
"I have never seen anything like that. I just can't believe what I just saw."
Amid confusing scenes, it appeared the incident may have unfolded in several locations, including on the busy Westminster bridge where tourists take pictures of Big Ben and other attractions.
Reuters reporters inside parliament said a large number of armed police, some carrying shields, were pouring into the building.
U.S. President Donald Trump told reporters at the White House he had been briefed on events in London but gave no details.
The incident took place on the first anniversary of attacks on Brussels in Belgium.
Britain is on its second-highest alert level of "severe" meaning an attack by militants is considered highly likely.
London’s metropolitan police were reaching out to the public via radio and twitter to ask that everyone use “common sense and restraint,” in circulating pictures and videos of those injured during the incident.
At the same time, they were also calling on the public to come forth with any and all information. “If you have photos or film of the incident in Westminster please make sure you pass them to us,” they said in a bulletin.
