A double bomb attack in Syria's city of Idlib on Monday killed 16 civilians, and six fighters, 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 51, updating an earlier casualty toll.

Idlib, the last major part of Syria still outside the control of the regime of Bashar al Assad, is held by an alliance led by Hayat Tahrir al Sham (HTS).
HTS took administrative control of the whole of the region last month.
A local office of the "Salvation Government," an administrative body created by HTS, is located on the street targeted by Monday's attack.
Idlib has been protected from a massive regime offensive since September by a buffer zone deal agreed by Russia and 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 regime controls nearly two-thirds of the country.
Regime shelling kills five Five civilians were killed in artillery shelling by regime forces and Iran-backed militias in Syria's northwestern Idlib province on Tuesday, according to the White Helmets civil defense agency.
The attacks targeted the city of Khan Shaykhun and Maaret al-Numan, Mustafa Haj Yousuf, the White Helmets official in Idlib, said.
He said six other civilians were injured in the shelling.
Regime attacks in the de-escalation zone of Idlib are estimated to have killed at least 68 civilians and injured hundreds since the start of this year.Source: trtworld.com
