BEIRUT (Reuters) – Dozens of trucks carrying humanitarian aid set off on Thursday for the town of Rastan in Syria’s Homs province for a delivery to a besieged area where supplies have not been able to enter for months, the Red Crescent said.

Rastan was one of the first areas to be bombed by Russian warplanes when Moscow intervened in the five-year Syrian war in September. New government air strikes have targeted the area in recent days as a partial truce in western Syria has unraveled.

A spokesman for the Red Cross, which was to deliver the aid alongside the Red Crescent, said Thursday’s convoy included 65 trucks carrying food and medical aid. He said it was one of the largest joint humanitarian aid deliveries in Syria.

United Nations and Red Cross aid deliveries have reached a number of besieged areas in Syria this year, including during a U.S.-Russian-brokered cessation of hostilities agreement that took effect in February.

The truce is now in tatters after fighting intensified, and peace talks in Geneva appeared to collapse this week.

Fresh fighting has displaced tens of thousands more people in recent days near the northern city of Aleppo, the United Nations says. Many locations besieged by government forces and their allies, Islamic State fighters and other insurgents remain hard to reach, aid agencies say.
