A military transport plane carrying members of the Algerian armed forces and their relatives crashed into a mountain on Tuesday, killing 77 people, the worst air disaster in the North African country in a decade.

State television showed footage of the wreckage of the plane near the village of Ouled Gacem in eastern Algeria, smoke rising from the site and emergency crews scouring the forested area for survivors and bodies.

“I saw the military plane crashing, and it was cut into two pieces,” Mohamed, a fireman told Reuters at Ouled Gacem, near the crash site in Oum El Bouaghi province, 500 km (300 miles) east of Algiers.
