4 Dead After Attack Near U.K. Parliament

The head of counterterrorism at London's Metropolitan Police says four people have died in the terror incident in London, including an attacker and a police officer.

Mark Rowley says some 20 people have been wounded and Parliament was locked down. A search is underway to make certain no other attackers are in the area — though police believe there was only one attacker.

Rowley said the dead policeman was one of the armed officers who guard Parliament. The other victims were on Westminster Bridge.
