The crash of a military helicopter in Ghana on Wednesday killed all eight people aboard including the West African country's defense and environment ministers and other top officials, the government said.

The helicopter had taken off from Accra, the capital, en route to a mining conference when it went “off the radar,” the armed forces said.

Eight people, including Ghana ministers and members of Parliament, were killed Wednesday when the helicopter they were aboard crashed in the West African nation's southern Ashanti region. There were no survivors.
