"The scene may be in place for much of today," police said. 

The motive for the stabbing isn’t clear. 

One witness was quoted by the BBC as saying that an "angry man" took out a knife and started "hitting a young man."

"All the people there started to run scared," he said, describing the panic outside the British Museum.

"We started to run to the museum gate to tell the people there what was happening and to call the police," the witness told the BBC. "Everybody was telling them 'call the police, call the police, a man is stabbing a man'."

Another witness, identified as a 27-year-old American woman, said she was just about to get into a line to enter the museum when she was motioned away by police.

"A cop directly in front of us told us we needed to leave and that the crime scene was large," she told the BBC.
