Trump Has Been Briefed about Incident at London Bridge

U.S. President Donald Trump has been briefed about the incident at London Bridge in Britain by his national security team, the White House said on Saturday.

The national security team "will continue to provide updates" to the president, White House spokesman Sean Spicer said in a message posted on Twitter.

British police rushed to an incident on London Bridge on Saturday after witnesses said a van ploughed into pedestrians and one woman told Reuters she saw people who may have had their throats cut.

British Transport Police said casualties were reported after an incident that may have involved a van and a knife attack, the BBC said, while the London Ambulance Service said it was sending multiple resources to the incident.

Police said armed officers were also responding to an incident in the nearby Borough Market area of the city.

One witness told Reuters that she saw what appeared to be three people with knife wounds and possibly their throats cut at London Bridge. Reuters was unable to immediately verify her account.
