A senior police commander says the attack at London’s Parliament has been declared a terrorist incident and “a full counterterrorism investigation is underway.”

Commander B.J. Harrington says “a number” of people have been injured, including police officers.

Officials say a man with a knife attacked a police officer at Parliament and was shot by officers.

There are also reports of a vehicle hitting pedestrians on nearby Westminster Bridge.

Witnesses said a vehicle struck several people on the bridge, and photos showed a car plowed into railings.

A man outside Britain’s Parliament says he couldn’t believe what he was seeing when a man with a big knife started plunging the weapon into a policeman.

Rick Longley also told the Press Association that someone also crashed a car into a fence near Big Ben and “took some pedestrians out.”

A doctor says a woman has died and about a dozen people are hurt, some with “catastrophic” injuries, after a vehicle apparently hit pedestrians on Westminster Bridge, near Parliament.

Colleen Anderson of St Thomas’ Hospital says a female pedestrian has died.

“There were people across the bridge. There were some with minor injuries, some catastrophic. Some had injuries they could walk away from or who have life-changing injuries,” she said.

Anderson said there might be a dozen injured in all.

Britain’s Parliament complex remains in lockdown.

Prime Minister Theresa May was at Parliament when the incident began, but her office says she is safe.

Today is the first anniversary of the attacks at the airport and on the subway in Brussels that killed 32 people and injured 300 others.
