One person has died after a huge crane collapsed onto a house in east London and people are trapped inside.

Four people were treated by London Ambulance Service, with two taken to hospital with head injuries and the other two assessed at the scene.

London Fire Brigade said a 20-metre crane collapsed onto a terraced house in Bow, adding that crews are working to free people who are trapped.

The fire service said it had taken 14 999 calls to reports of a crane falling on to a building in Gale Street and urged people to avoid the area.

A video posted on the LFB Twitter page shows a terraced house with part of the roof caved in.

London Ambulance Service tweeted: “We have a number of crews and specialist resources including @LAS_HART on scene at an incident in Watts Grove in #Bow, east London, where a crane has collapsed.”
