Woman killed, five others injured in London knife attack

DEVELOPING: 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.
