Cause of Venezuelan chopper crash is under investigation

Venezuelan authorities are investigating the cause of a helicopter crash that killed seven military officers while they were while heading to a state where President Nicolás Maduro was visiting troops.

The crash of the Cougar helicopter outside 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 between protesters and police.

The armed forces say the chopper that crashed was heading to San Carlos in Cojedes state, near a military base where Maduro addressed cadets on Saturday. The statement doesn't say if the chopper was part of the presidential delegation.

The Venezuelan opposition plans a memorial service later Sunday for those killed in street fighting over the past week.
