Four dead, including assailant, in UK terror attack

A police officer was among three killed Wednesday in a suspected terrorist attack outside Britain's parliament by an assailant who was then shot dead by armed police, Britain's top anti-terror officer said. Mark Rowley said the two other victims died on Westminster Bridge in London after the attacker mowed down pedestrians in a car, leaving at least 20 people injured in total. "Sadly I can confirm that now four people have died," the Metropolitan Police assistant commissioner told reporters outside Scotland Yard police headquarters.
"That includes the police officer who was protecting parliament and one man who we believe to be the attacker, who was shot by a police firearms officer. "We have declared this as a terrorist incident and the counter-terrorism command are carrying out a full-scale investigation into the attacks." He said the assault began when a car was driven over Westminster Bridge next to the Houses of Parliament, hitting and injuring several members of the public, including three police officers returning from a ceremony.
