At least 51 people were killed as a bus plunged into a ravine early Monday in Guatemala City, officials said.
At least 20 more were seriously injured, they said.
City officials said the incident occurred when the bus veered off a highway and went into a ravine.
Photos released by fire officials showed the bus upside-down in the ravine as they pulled passengers from the wreckage.
In a statement, Guatemalan President Bernardo Arevalo said the country’s army and disaster relief agency would aid in the response.
Arevalo also said he would declare a period of national mourning.
