Apologies for the hurried previous post from my phone, I am now at a PC, and here is the latest:
From The Associated Press:
Dennis Burns, who was just entering Parliament for a meeting, told the Press Association he heard a radio message saying an officer had been stabbed. Police and security rushed outside as he was going in.
“When I got inside I was wondering what the hell was going on and I saw dozens of panicked people running down the street,” he said. “The first stream was around 30 people and the second stream was 70 people.
“It looked like they were running for their lives,” he said.
On the bridge, witnesses said a vehicle struck several people, and photos showed a car plowed into railings.
The former Polish foreign minister Radoslaw Sikorski posted a video on Twitter that showed people lying injured on the bridge.
Sikorski, a senior fellow at Harvard Centre for European Studies, says he saw at least five people lying on the ground after being “mown down” by a car.
