MANILA, Philippines, June 14 (UPI) -- A bus with Iranian medical and nursing students aboard plunged into a ravine near Cebu City in the Philippines, killing at least 20 people, officials said.
At least 30 other people were injured, investigators said.
Officials said the bus plummeted about 98 feet into a ravine Sunday while negotiating a downhill section of the Trans Central Highway about 3 miles from Balamban, the Philippine Daily Inquirer reported Monday.
"So far, we have retrieved 20 bodies. I can't confirm their nationality yet, but initially, most of them were Iranian nationals," Cebu provincial Police Director Erson Digal said.
Digal said the bus was traveling from Cebu City to Balamban, suggesting it may have been on a sightseeing trip.
Balamban Mayor Alex Binghay said a shipbuilding company in Balamban dispatched a crane to lift the wrecked bus owned by Cattleya Bus Co. from the ravine.
Binghay said witnesses told him they thought the driver wasn't familiar with the serpentine road and that the vehicle was traveling at a high rate of speed as it was going downhill.
