More than a dozen people were killed in blasts claimed by ISIS in a Damascus suburb on Saturday. The Syrian Observatory for Human Rights, a monitoring group, has put the death toll at more than 20 after a suicide bomber and a car bomb struck near the country’s holiest Shi’ite Muslim shrine. At least 13 of those killed were civilians. ISIS, which considers Shi’ites to be sworn enemies of Islam, took responsibility for the blasts and said two suicide bombers had been involved and a car bomb set off. The target of the attack, the Sayeda Zeinab shrine, is a hot spot for Shi’ite militia fighters.
