A car bomb killed at least 27 people including three children on Monday in the Syrian town of Darkush in the northwestern Idlib province, near the Turkish border, a rights group said.
The Syrian Observatory for Human Rights said the the toll was expected to rise, as a large number of people suffered serious injuries, according to Agence France-Presse.
The NGO also said at least one child was among the dead.
Activists from the Syrian Revolution General Commission network said the blast took place in the market area of the Darkush town which is under Syrian opposition control, AFP reported.
Videos posted by activists online showed the aftermath of the blast with one car ablaze and residents carrying bodies on makeshift stretchers and extensive damage to buildings around the blast site.
Darkush is just a few kilometers from the border with Turkey.
