Patients moved in hospital fire

About 200 people were moved out of the hospital

Dozens of patients were removed from hospital wards after two ambulances caught fire and exploded.

About 200 people were ordered to leave St Helier Hospital in Carshalton, south London, after the fire broke out at about 1650 BST.

A firefighter suffered a slight burn to his neck and three hospital staff were treated for minor injuries.

Firefighters had to make six oxygen tanks safe before people could return.

A spokesman for the hospital said: "A major incident was declared at St Helier Hospital when two ambulances caught fire.

"As part of the hospital's emergency procedures, patients from neighbouring wards were moved to avoid the smoke. These patients were moved back a couple of hours later."

The cause of the fire is being investigated.
