At least 22 people have been killed and there are fears the toll could rise after a car bomb attack in the Syrian rebel-held town of Darkush, in Idlib province, close to the border with Turkey.
Security sources said the device was powerful, and that dozens had been wounded, leaving many of them in a critical condition.
A local reported that the area had been cleared of government troops for months, but that the security situation remained tense.
No-one has yet claimed responsibility for the attack, which left an entire street shattered, cars ablaze, and bodies lying in the street. Stretchers were improvised as medical services struggled to cope.
