At least 41 people were killed in the past 24 hours in an attack carried out by the Islamic State at a military airport in the Syrian province of Aleppo, a monitor group said on Monday.
The London-based NGO, Syrian Observatory of the Human Rights, said that among the dead were 15 government troops and this included 12 police officers, while 26 IS jihadists were also killed in the offensive launched on Sunday by the IS to gain control of the airport.
The monitoring group said that the clashes were going on in the area. The IS proclaimed a caliphate in territories under its control in Syria and Iraq in June 2014.
