At least 53 people are reported to have been killed in air strikes on a rebel-held town in northern Syria.
A market was hit, with video on social media showing widespread destruction. Rubble covers the streets and panicked civilians are seen carrying away the injured.
Eyewitnesses say there were three separate strikes.
It is not clear whether the strike was carried out by Syrian government warplanes or those of its ally Russia.
The town is located in an area of Aleppo province that is part of a “de-escalation zone” established earlier this year by Russia and Iran – which support the Syrian government – and Turkey, which backs the rebels.
The zones are credited for creating a drop in violence, but intermittent clashes have continued while humanitarian access is minimal.
The area is largely held by opposition forces and a jihadist group formerly affiliated to Al-Qaeda.
