At least 12 people have been injured after a bus crashed into a tree in east London. Emergency services were called onto the scene on Station Road in Manor Park, Newham, with London's Air Ambulance and the London Fire Brigade both in attendance.

Authorities said that 10 passengers had been taken to hospital, according to the Daily Mail. A spokesperson for the Ambulance service said a man in his 40s with a head injury and a woman in her sixties with a hip injury had been taken to Royal London Hospital in a serious condition.

Metropolitan Police are currently not treating the incident as suspicious and no arrests have been made. However, inquires continue, a spokesman told the Daily Mail.

Upon arrival, the London Fire Brigade closed down the A117 Forest Drive road with local police officers to enable the air ambulance to land on Capel Road nearby. The 15 people on the Walthamstow-bound W19 bus were then treated by the ambulance service at the scene.

"We were called at 11:59am to reports of a road traffic collision involving a bus and a tree at Manor Park station," a spokeswoman for London Ambulance Service said in a statement. "We sent a number of resources to the scene including six ambulances, four duty officers, our hazardous area response team, London's Air Ambulance and our emergency planning team."

Pictures from the scene show the single-decker bus crumpled against a substantial trunk, with much of its left-hand side crushed or ripped off. Police said local road closures were in place and urged motorists to avoid the area.
