A passenger bus crash north of Quito claimed the lives of at least 28 people today. Authorities say the vehicle was likely speeding, and ran off the road into a ravine. The bus was travelling to a festival in the rural community of Guajara.

Authorities at the National Risk Management reported specifics of the casualties: 15 men, 11 women and 2 children.

Fire chief colonel Marco Antonio Hadathy announced earlier that all of the dead and injured have been evacuated.

“The dead are in the morgue of the Hospital San Vicente de Paul,” he said. Most of the injured were checked into various medical centers in the area, and three were taken to Quito’s severe trauma unit by helicopter.

The bus “hit an embankment, bounced and fell into a ravine twenty feet deep,” Hadathy said to local news sources, adding that the rain was partly to blame. “All the passengers ended up stacked in the cabin of the bus, which kept the wheels up.”

The officer added that he will investigate the causes of the accident, but Fernando Castile, secretary of National Risk Management, told other sources the accident was likely caused by the negligence of the driver.
