A car bomb has killed 34 people and injured more than 50 others in a government controlled village in central Syria.
The blast took place in Hurra, a village close to the city of Hama inhabited by members of the Syrian President Bashar Al Assad's Alawite tribe.
AFP said responsibility was claimed by the Islamic Front, a confederation of a Islamist groups fighting Assad's government.
A video put out by the group's Youtube account showed a large yellow mushroom cloud lighting up the night sky.
Sky News is unable to independently verify whether the video shows the car bombing.
Syria's state news agency SANA described the car bomb as a "terrorist" attack, blaming it on rebels.
The Islamic Front said on Twitter that a "remotely guided car" had been used to target a "gathering of Assad militia".
The Syrian Observatory for Human Rights, an anti-Assad monitoring group, said there were overnight clashes between government forces and Islamist fighters in the area around Hama, as well as bombings by the Syrian army.
The Islamic Front is one of a number of rebel groups fighting government forces in Syria. It is separate from the western-backed Free Syrian Army and the Islamist militant group ISIS, currently also fighting in neighbouring Iraq.
At least 100,000 people have been killed in the three-year conflict in Syria, according to United Nations. More than three million have fled the country as refugees and 6.5 million have been internally displaced.
A crater left after the blast in HomsOn Thursday, a car bomb exploded in the city of Homs, south of Hama, killing at least six people in a neighbourhood populated by Alawites.
It was the second attack in Homs - Syria's third largest city - in less than a week. No one claimed responsibility but state television blamed it on rebels.
Syrians have begun returning to the Old City of Homs, which has been left shattered by months of attacks by government forces.
Meanwhile, in neighbouring Lebanon, which is said to be suffering a spill-over from the war in Syria, a suicide bomber killed at least two people at a checkpoint on the main highway from Beirut to Damascus.
A Lebanese security source told Reuters that the bomber appeared to target a convoy which included a top security chief. The apparent target was unharmed, the source said.
The attack, in Dahr el Baydar in the Bekaa Valley, east of Beirut, also left several wounded.
