津巴布韦反对派领导人在美国坠机身亡

U.S. authorities are investigating a helicopter crash which killed Senior Zimbabwe opposition leader Roy Bennett, his wife and three others.

Police say the aircraft went down Wednesday night, in a remote mountainous area in the state of New Mexico, close to the border with Colorado.

Another passenger who was injured in the crash managed to get away and call for help.

It is unclear what Bennett was doing in New Mexico.

The 60 year-old Bennett was an activist for causes helping the poor and a fierce opponent of longtime president Robert Mugabe, who was forced to resign late last year.
