At least 28 people were killed and dozens of others injured on Thursday in airstrikes on a refugee camp in a rebel-held area in northern Syria, a monitoring group said.
The Syrian Observatory for Human Rights said that the strikes targeted a camp in the town of Sarmada in Idlib province near Syria's border with Turkey.
The dead included women and at least seven children, the watchdog said.
The aircraft that carried out the strikes were not immediately identifiable.
The bombardment came hours after a temporary truce took effect in the northern city of Aleppo, which has been the battleground of deadly fighting between regime forces and rebels in the past two weeks.
