Infighting between rival insurgent groups is raging on in Syria. Opposition sources say that foreign-backed militants have seized the headquarters of al-Qaeda-linked insurgents in the northern city of Aleppo. The sources added that members from several insurgent groups have taken control of a children\'s hospital in Qadi Askar district that is the headquarters of the Islamic State of Iraq and the Levant in Aleppo. Meanwhile, other reports from Syria say at least 20 militants have been killed in a car bomb near the northern city of Dakoush. The attack was reportedly carried out by militants from the I-S-I-L. The recent tension among militant groups fighting the Syrian government has been the deadliest since the conflict began in the war-torn country back in March 20-11. Show Less >>
