UN peacekeepers said at least 29 people were killed when a large truck carrying people and merchandise collided with three pickups in southern Haiti. More than 50 people, mostly women and children, have been treated for injuries from Saturday's crash east of the town of Cavaillon. UN spokesman Vincenzo Pugliese said Sunday that the truck was unable to stop when a pickup truck slowed suddenly. It plowed into two vehicles, swerved into an oncoming third and flipped over. Peacekeepers treated and evacuated many of the injured. Five were taken by UN helicopters to a Port-au-Prince hospital.
