Syrian coastal cities of Jableh and Tartous has been rocked with bomb blasts killing more than 100 people on Monday.

The Islamic State claimed responsibility for the attacks in the Mediterranean cites which has up till now escaped the worst of the conflict, saying it was targeting supporters of President Bashar al-Assad.

The Syrian Observatory for Human Rights said that “Scores were wounded in at least five suicide attacks and two car bombs, which is the first assaults of their kind in Tartous, where government ally Russia maintains a naval facility, in Jableh”.

State media confirmed the attacks but gave a lower toll.

Fighting has increased in other parts of Syria in recent weeks as world powers struggle to revive a threadbare ceasefire in western Syria and after peace talks in Geneva this year broke down.

State media reported that “a car bomb and two suicide bombers attacked a petrol station in Tartous”.

“In Jableh, one of the four blasts hit near a hospital”, state media and the Observatory reported.
