More than 100 people are believed to have been killed in a series of blasts in the Syrian coastal cities of Jableh and Tartous, with Islamic State militants claiming responsibility for the attacks.
Bomb blasts killed more than 100 people in the Syrian coastal cities of Jableh and Tartous on Monday, monitors said, in a government-controlled area that host Russian forces.
Islamic State claimed responsibility for the attacks in the Mediterranean cites that have up to now escaped the worst of the conflict, saying it was targeting supporters of President Bashar al-Assad.
Scores were wounded in at least five suicide attacks and two car bombs, the Syrian Observatory for Human Rights said, the first assaults of their kind in Tartous, where government ally Russia maintains a naval facility, and Jableh.
State media confirmed the attacks but gave a lower toll.
