Senator Jean Marie Ralph Fethiere stepped out of a white truck near parliament in the capital Port-au-Prince after several protesters yanked open his passenger-side door while gesturing and yelling at the lawmaker, Reuters footage showed.
Fethiere, wearing a black suit jacket and jeans, pulled out a handgun and fired several shots, sending the cluster of people around his car fleeing in all directions.
He then got back inside the vehicle, which sped out of the parking lot.
