A convoy carrying aid for earthquake victims has crossed the Turkey-Syria border, sources said on Thursday.
Six aid lorries were reported to have arrived in north-western Syria a day after the UN said it hoped to make deliveries there for the first time since the earthquake struck on Monday.
The UN said it had halted assistance passing through Turkey for logistical reasons.
Syrian opposition groups on Wednesday said the Bab Al Hawa crossing from Turkey, the only UN-recognised route for aid into north-western Syria, had reopened.
The four million people in the region, including the internally displaced population living in tents, are suffering in low winter temperatures. Some roads have been blocked by snow.
