An Algerian military plane has crashed during a training flight, killing two crew members, the defense ministry said on Thursday. The Russian SU 24 aircraft crashed late on Wednesday in an inhabited agricultural area in the northern province of Tiaret, around 250 kilometers southwest of Algiers, the ministry said in a statement. The pilot and co-pilot were killed during the "night-time training flight", it said, adding that it was investigating the cause of the accident. It was the first such incident since the countrys worst military plane crash that killed 257 people in April last year at a military base near Algiers.
