At least 34 people were killed and about a dozen injured in northern Haiti late on Saturday after a bus drove into a parade of pedestrians while fleeing from an accident, the country's civil protection authorities said on Sunday.
The bus, which was traveling from Cap Haitien to the capital Port-au-Prince, initially hit two people in a town outside Gonaives in the north of the country, killing one, said Joseph Faustin, civil protection head in the Artibonite department.
The bus driver then continued into a crowd of people participating in a Rara festival, an Easter season Haitian musical celebration.
It was not immediately clear what caused the accident.
Faustin said angry festival-goers then attacked the bus and tried to burn it before police rescued the passengers aboard. The bus driver fled and was being sought. He said the cause of the accident was unclear.
The injured were being treated at a hospital in Gonaives, about 60 miles (100 kilometers) northwest of the capital.
President Jovenel Moise called for an investigation into the incident.
"The head of state sends ... sincere condolences to the victims' families and loved ones," he added.
