The death toll in a bus accident near Manila has risen to 13 after three more victims died in hospital.
Thirty-eight other people were injured, including the bus driver who was severely injured, according to Carlos Inofre, chief of the town's Disaster Risk Reduction and Management Office.
The passenger bus, with a little over 50 people on board, rammed into an electric post along a highway in Tanay, about 38km east of Manila, on Monday.
Inofre said all the fatalities are students from a college in suburban Quezon City.
The bus appeared to have suffered a brake malfunction while negotiating a downward-winding road in the village of Sampaloc, Inofre said.
"The bus could have been running fast when it hit the post since its roof was almost detached" Inofre told a local radio station.
The victims were supposed to join in a camping tour at a resort in Tanay as part of their school activities.
