Manila: At least five people including a 2-year-old boy were killed and 15 others were injured on Wednesday when a passenger bus rammed a stalled truck along the highway in eastern Philippines’ Camarines Sur province at the start of the Easter week exodus of vacationers to provinces, police said.

Police Superintendent Vicente Marfori said the driver of the bus from Manila is under investigation at the police station of Libmanan town, where the accident happened.

The whole right side of the bus was dislodged by the collision.

Marfori said the driver of the truck was in shock in a hospital.

The four-day Easter week holidays officially start on Thursday but vacationers have already started travelling to the provinces for the long break.

Road accidents are common in remote areas in the Philippines, largely because of poor vehicle maintenance, bad road conditions and poor implementation of safety measures.
