Islamic State militants have shot down a Syrian warplane, according to this video posted to a social media website.<br/> <br />It's the first time the group, which used anti-aircraft guns, has blown a fighter jet from the sky.<br/> <br />Fighters could be seen gathering up pieces of the aircraft, which crashed outside the IS stronghold of Raqqa, some 250 miles northeast of Damascus.<br/> <br />Syrian forces have been bombing the area daily since Islamic State militants seized the Iraqi city of Mosul.<br/> <br />The Sunni Extremist group has emerged as the dominant opposition group, forcing the government to fight on a number of different fronts. Within hours of downing the jet in Raqqa, IS targeted this military complex in Aleppo. Fighters are well aware that a victory here, in the country's largest city, could signal a tide change and put them closer to their goal to create an Islamic caliphate across Syria and Iraq.
