Four people died and 11 were injured in a highway accident Monday in the eastern Cuban province of Granma, state television reported.

The accident occurred when a small bus on the road from Bayamo, a city in Granma, to Holguin clipped the rear wheel of a cart, went out of control and hit a tree.

Ciro Estrada, director of Carlos Manuel de Cespedes Hospital where the injured occupants of the bus were taken, said that 10 of them suffered "head and thoracic injuries" and that one of the patients had to be operated for a severe head injury.

In 2011 there were 11,604 recorded traffic accidents that left some 8,240 people injured, according to a report by the National Transit Authority released last week.

Traffic accidents are in fifth place among the causes of death on the island. EFE
