The so-called White Helmets civil defense group and residents said the blast took place in Jisr al-Shughour, located about 330 kilometers (200 miles) north of the capital, Damascus, on Wednesday as several residential buildings collapsed as a result of the act of terror, Presstv Reported.
Ahmad Yaziji, a member of Western-backed White Helmets, who have been accused of cooperating with Takfiri militants and staging false flag gas attacks, said at least 17 people were killed and at least 27 people, mostly civilians, were injured. He noted that the number of casualties is expected to rise as some of the injured are in a critical condition, and rescue workers are recovering bodies from under the rubble.
The so-called Syrian Observatory for Human Rights said the cause of the blast in Jisr al-Shughour was not immediately clear.
“It is not known until now whether it was a car bomb, or the explosion of a car carrying explosives,” head of the Britain-based monitor group Rami Abdel Rahman noted.
Under a deal reached following a meeting between Turkish President Recep Tayyip Erdogan and his Russian counterpart Vladimir Putin in the Black Sea resort city of Sochi on September 17, 2018, all militants in a demilitarized zone, which surrounds Idlib and also parts of the adjacent provinces of Aleppo and Hama, were supposed to pull out heavy arms by October 17 that year, and Takfiri groups had to withdraw by October 15.
The National Front for the Liberation of Syria is the main Turkish-backed militant alliance in the Idlib region, but the Takfiri Hayat Tahrir al-Sham (HTS) terrorist group, which is a coalition of different factions of terror outfits, largely composed of the Jabhat Fateh al-Sham Takfiri terrorist group, holds a large part of the province and the zone.
The HTS, which is said to be in control of some 60 percent of Idlib province, has yet to announce its stance on the buffer zone deal.
It is estimated that between 10,000 and 15,000 members of different factions of armed groups, which Syria, Russia and Turkey consider terrorists, are active in the volatile province, which is home to around three million inhabitants.
Russia believes that a buffer zone would help stop attacks from Idlib-based militants on Syrian army positions and Russia's military bases in the flashpoint region.
Car bomb hits Syria capital, killing civilian
Separately, one civilian was killed and five others were injured as a car rigged with explosives blew up in the Syrian capital.
“One civilian was killed and five others injured in an explosion in the area of Nahr Aisha in Damascus,” Syria’s official news agency SANA said.
“Investigations showed that terrorists planted an explosive device inside a Peugeot car, killing the driver,” it added.
Five people in the vicinity were wounded and taken to Damascus Hospital to receive medical treatment, it said.
Syria has been gripped by foreign-backed militancy since March 2011. The Syrian government says the Israeli regime and its Western and regional allies are aiding Takfiri terrorist groups wreaking havoc in the country.
