Woman killed, five others injured in London knife attack

A man attacked several people with a knife in central London Wednesday evening, killing a woman and injuring five other people in what police described as a possible terror attack.

A Metropolitan Police spokesman said officers were called to Russell Square at around 10:30 p.m. local time (5:30 p.m. ET) for a report of an armed man. They found "up to six people injured", including a woman who was pronounced dead.

"Terrorism is one possibility being explored at this stage," the statement added.

Authorities said one man was arrested after police deployed a Taser. The conditions of the injured victims were not immediately clear.

A police spokesman said additional units had been deployed to the area, "to provide reassurance." The spree came hours after police announced that an additional 600 armed officers would be deployed across London following recent terror attacks in continental Europe.
