At least 20 people were killed and three others injured when a bus plunged off a cliff Tuesday in Colombia's northwestern province of Choco, authorities said.
The bus fell off a 120-meter cliff after reportedly avoiding a landslide on the road connecting Medellin, capital of Antioquia province and Quibdo, capital of Choco, said Rafael Montoya, mayor of the municipality of Carmen de Atrato, Xinhua reported.
"We are still not sure whether there are more deaths, while only three have been confirmed injured, including the bus driver and a soldier. We have not been able to reach the bottom of the cliff to rescue the victims," Montoya said.
The bus departed Medellin on Monday evening with 36 people onboard, he added.
