A bus fell into a steep ravine in a remote northwestern area of the Andes in Peru on Thursday, leaving at least 20 people dead and 33 injured.
Local authorities said the accident occurred when the bus went off the road in the province of Pataz, plunging some 100 meters (984 feet).
Video images of the scene of the accident show the wreckage of the bus on a hillside.
"We are lending support to the local municipality of Pataz with healthcare resources and local police efforts," Pataz Mayor Omar Iparraguirre said.
Ambulances carried the wounded to hospital in the nearby town of Tayabamba.
