Separately, London’s ambulance service said it had taken at least 20 people to the hospital and treated others on the scene after an attack at the London Bridge area.

“We have taken at least 20 patients to six hospitals across London following the incident at London Bridge,” the London Ambulance Service’s assistant director of operations, Peter Rhodes, said in a statement. “We have also treated a number of people at the scene for less serious injuries.”

Separately, London police are unsure if all the militants involved in a deadly attack have been
accounted for, Reuters said, citing Sky News.

A police spokesman declined to comment to Reuters about the report.
