A double bomb attack killed 13 people, including 10 civilians, in Syria's jihadist-held city of Idlib on Monday, a war monitor said. The first blast was caused by a bomb planted under a car in the main city of the Idlib region, the Syrian Observatory for Human Rights said.
After ambulances arrived at the site, a motorcycle bomb then detonated, the Britain-based monitoring group said. There was no immediate claim of responsibility for the attack, which the Observatory said also wounded at least 25.
Idlib, the last major part of Syria still outside the control of the regime of President Bashar al-Assad, is held by an alliance led by Syria's former Al-Qaeda affiliate. Hayat Tahrir al-Sham took administrative control of the whole of the region last month, after overpowering smaller Turkey-backed factions.
Idlib has been protected from a massive regime offensive since September by a buffer zone deal agreed by regime ally Russia and rebel backer Turkey. But it has been hit by sporadic government shelling. Eight years into the conflict that has killed more than 360,000 people, Assad's government controls nearly two-thirds of the country.
