An air strike has hit a refugee camp in northern Syria, near the border with Turkey, killing and wounding dozens of people, Syrian pro-opposition activists said.
The Britain-based Syrian Observatory for Human Rights said a camp in near Sarmada, in the north-western Idlib province near the Turkish border, was struck on Thursday afternoon.
It was not clear who carried out the air strike and the observatory did not immediately have a breakdown of the casualties.
The Local Coordination Committees (LCC) network said first responders are at the site, extinguishing fires that have erupted in the impacted zone.
A photo that was posted on the LCC's Facebook page shows at least a dozen tents burned to the ground.
