Sudanese state media say a military helicopter has crashed in the country's western Darfur region, killing all five on board.
It's the second military helicopter crash in Sudan in less than a week.
Army spokesman Col. Khaled al-Sawarmy says technical failure caused the MI-17 helicopter to crash as it was about to land at the airport in the city of El Fasher on Monday morning.
The official SUNA news agency says three officers, including a major, and two privates died.
Last Wednesday, an MI-24 helicopter gunship on a training mission burst into flames as it was taking off from a military airport near the capital Khartoum, killing one crew member. Technical failure was also said to be the cause of that crash.
