At Least 20 Dead After IS Attack at Syria Border Crossing by VOA News The Islamic State group claimed responsibility for a bomb blast that killed at least 20 people, most of whom were Turkish-backed opposition fighters along Syria's northwestern border with Turkey. A suicide car bomber targeted a convoy of rebel troops near the border crossing in the village of Atmeh, just a short distance away from where the rebels and the jihadist group had been fighting along another stretch of the border. The Syrian Observatory for Human Rights, a British-based non-profit group, put the number of dead at 21. The Islamic State group took credit for the attack in an online statement. Those killed include a judge and another top civil judicial figure from the rebel-held eastern Aleppo, according to a rebel official. One witness told Reuters most of those killed in the blast were members of the Failiq al-Sham group, which has been fighting alongside Turkish soldiers to defeat the IS group.
