A Syrian alliance of Islamist jihadist groups known Tahrir al Sham said on Sunday it was responsible for two suicide attacks in the capital Damascus that killed and injured dozens of Shi’ite visitors. In a statement, the group said the attack targeted “Iranian militias” and pro-government defence militias in revenge for what it said was Iran’s role in supporting President Bashar al Assad’s “tyrannical rule,” holding them responsible for “killing and displacing” Syrians.
