Protesters set a police vehicle on fire during demonstrations in Port-au-Prince on Wednesday, after agents from the National Palace General Security Unit reportedly shot at them.
According to reports, protesters clashed with the police after attending the funeral of allies who have died in demonstrations calling for President Jovenel Moise to resign.
Uniformed agents are seen shooting and running after protesters. Several people were injured. Footage shows one man bleeding from his arm and entering an ambulance.
Haiti has been gripped by the fuel crisis since last year's collapse of the PetroCaribe agreement with Venezuela, which allowed Haiti along with other Caribbean countries to purchase subsidised fuel. Crippling shortages in September have triggered a massive anti-government movement.
