The UN said Friday that its first aid convoy in three years had reached Syria’s Deir ez-Zor city via road after government troops broke an extremist siege last week.

Trucks carrying “life-saving items” like wheat flour, canned foods and nutrition and maternal health items for 15,000 families reached Deir ez-Zor on Thursday, UN humanitarian agency spokesman Jens Laerke said in Geneva.

While the first from the UN, the convoy was not the first to reach the city since the siege was broken on September 5, with trucks carrying in food aid from the Syrian Trade Association last week.

The UN carried out 309 successful airdrops of aid during the siege, Laerke said Friday.
