MANILA, Dec. 26 (Xinhua) -- Four people were killed and at least 23 others injured after a passenger bus plunged into a ravine along a highway in Camarines Sur province on Luzon island in the Philippines on Friday morning, police said.
The bus, which was carrying 27 people, including the driver and the alternate driver, was traveling southbound from Metro Manila, and the accident occurred in the municipality of Del Gallego, police said.
Police said the vehicle veered off the road and fell into a ravine, and that trees below the ravine helped stop the bus from falling further, which prevented more damage.
Police are conducting a full investigation to determine the cause of the crash. ■
