BEKASI, INDONESIA (REUTERS) - At least 10 people were killed, including some children, after a truck crashed on Wednesday near a bus stop outside a school in Indonesia's West Java province, police said.

The students were waiting at the bus stop after class in the city of Bekasi, when the truck veered towards them and crashed into two motorcycles and toppled a concrete communications tower, said traffic policeman Latif Usman.

Mr Usman said 20 children were also injured in the crash.

"We are conducting an investigation to assess if the brakes failed," said Mr Usman.

Another police official in Bekasi said the driver had been detained.

Images from the scene showed the communications tower had fallen across the road outside the school's gates and crashed into the bus stop on the sidewalk.
