The DAESH terrorist group has claimed responsibility for a suicide attack in the town of Salamiya in the Syrian province of Hama on Saturday.
The group released an online statement saying that one of its fighters had driven a car packed with explosives into a Syrian regime area before blowing himself up, killing 20 people and injuring 35 others.
The attack on the entrance to the town of Salamiya in eastern Hama came less than a day after a "cessation of hostilities" in Syria had been announced under a plan led by Russia and the US.
The US and Russia had agreed to call for a cessation of hostilities in Syria to begin on Feb. 27.
The proposal, however, excluded the DAESH terrorist group and the Al Qaeda-linked Nusra Front.
The London-based Syrian Observatory for Human Rights (SOHR) had earlier speculated that the attack was carried out by DAESH.
"The car bomb attack is not a breach of the truce because it occurred in an area where the cessation of hostilities agreement does not apply," the SOHR said.
The town of Salamiya is situated along front between Syrian regime forces and the DAESH terrorist group.
