Four people were killed last night due to the crash of a private helicopter, about 50 kilometers southeast of Montreal in the Canadian province of Quebec. Associated Press quoted Audrey-Anne Bélido, spokeswoman for the Quebec Provincial Police, as saying that the helicopter faced difficulties before crashing in the area, resulting in the death of the four people on board. The spokeswoman explained that the fire teams managed to extinguish the fire resulting from the accident within about an hour, noting that the police have not yet determined the identities of the victims or the causes of the helicopter crash. For its part, the Canadian Transportation Safety Board announced the dispatch of a team of specialized investigators to the accident site to begin technical investigations and determine the circumstances of the accident.
