Cause of Venezuelan chopper crash is under investigation

Venezuelan authorities investigated the cause of a helicopter crash that killed seven military officers headed to a state where President Nicolás Maduro visited troops.

The crash of the Cougar helicopter on the outskirts of Caracas on Saturday followed days of upheaval during which opposition leader Juan Guaidó called in vain for a military uprising to overthrow Maduro, and five people were killed in clashes.
