Humanitarian aid has started reaching multiple besieged areas of Syria after trucks filled with supplies left Damascus, the Syrian Red Crescent and the United Nations say.

At least 100 trucks rolled out of Damascus on Wednesday afternoon in the latest delivery of supplies to trapped residents in Madaya, Zabadani, Moadimayet al-Sham, Fuaa and Kafraya.

About 35 vehicles later arrived at the entrance to Moadimayet al-Sham, a rebel-held town near Damascus encircled by President Bashar al-Assad's forces, according to an AFP journalist at the scene.

Another 18 trucks departed for Fuaa and Kafraya, two towns in northwestern Idlib province besieged by rebels, the Red Crescent stated.

Al Jazeera reports that about 50 more trucks were scheduled to travel to Madaya and Zabadani near Damascus, which are under siege by the al-Assad regime. 

All in all, the UN says, the Syrian government approved access to seven besieged areas, after crisis talks in Damascus on Tuesday, and one week before a planned resumption of peace talks between Syria's warring parties.

The supplies included wheat and high-energy foods.

Previous aid convoys entered Madaya, Fuaa and Kafraya on January 11, after at least 28 people reportedly died of hunger-related causes in Madaya.

The UN has demanded unhindered access to all besieged areas of the country. It says that hundreds of thousands of people are trapped in different regions by fighting and deliberate blockades by various warring sides.

Meanwhile, Turkish President Recep Tayyip Erdogan said there was no question of Turkish forces stopping their bombardment of Syrian Kurdish fighters in northern Syria.

"We will not allow a new Qandil on our southern border" with Syria, Erdogan said in a televised speech in Ankara, referring to the mountain in northern Iraq which serves as a stronghold of the Kurdistan Workers Party.

Buoyed by the Russian bombing campaign in Syria, the Syrian army has come within 25 km of the Turkish border and says it aims to seal it off altogether, closing the main lifeline into rebel territory and recapturing Aleppo, Syria's largest city before the war.

The civil war in Syria that began in March of 2011 has killed more than 260,000 people, according to UN estimates.
