A Nigerian military helicopter crashed and exploded next to a college dormitory in the northeastern part of the country, the zone where troops are fighting an Islamic insurgency, the military and witnesses said Friday. All three crew members died, the military said.

Four days ago, the military reported a helicopter safely crash-landed minutes after take-off from Yola International Airport in Adamawa state.
