“At least 23 Syrian regime soldiers were killed in an attack on a military bus in the conflict-torn country’s east blamed on ISIS, a war monitor said Friday. ISIS “members targeted a military bus” in Deir Ezzor province on Thursday, said the Syrian Observatory for Human Rights, as remnants of the extremist group escalate their attacks. The attack killed “23 soldiers and wounded more than 10 others,” some of whom in critical condition, said the Britain-based group which relies on a wide network of sources inside Syria. The Observatory said “dozens of (other) soldiers” were missing.”
