The UN has successfully delivered food, medicines, and essentials to the Ukrainian city of Sumy, UN Secretary General's spokesman Stéphane Dujarric said.

"Colleagues from the humanitarian aid department have just informed us that a UN humanitarian convoy has reached Sumy safely," he said at a briefing on Thursday.

According to him, humanitarian aid is delivered to Sumy and nearby settlements for the second time, and this is the third successful delivery of international humanitarian aid to Ukraine over the past two weeks.
