A Syrian military helicopter has crashed in Aleppo province killing all crew on board, according to media reports.
AFP has reported Daesh as claiming to have shot down the government aircraft early Sunday, although state media reported that the incident was due to a technical problem.
The British-based monitoring group, the Syrian Observatory for Human Rights, confirmed Daesh's claim that it had brought down the aircraft near Kweyris airbase in the east of Aleppo province.
It is unknown how many people were on board.
Daesh accounts on the social media site Twitter said that the group had shot down the helicopter using anti-aircraft missiles.
