Madaya Syria:The first trucks of aid entered the besieged Syrian town of Madaya on Monday where more than two dozen people have reportedly starved to death as the UN called for hundreds to be evacuated for medical treatment.

The Syrian Arab Red Crescent said 44 trucks loaded with food and other aid entered the rebel-held town late afternoon while 21 other trucks went to the government-controlled towns of Fuaa and Kafraya.

Tearful women and children bundled up against the cold waited in the dark for the trucks bringing vital supplies after six months encircled by President Bashar al-Assad's forces.

"Our children are starving our bodies are trembling" Ghaitha Assad a 27-year-old resident told AFP.

"We have no food -- even bread. There is no water no electricity no heating. Our children cry all night we are unable to find anything to feed them."

The UN World Food Programme said the supplies could feed more than 40000 people for one month and the ICRC said it was taking enough medicine for three months.

"I saw a young man killing cats and presenting the meat to members of his family as rabbit" Hiba Abdel Rahman 17 told AFP.

"Some people went through garbage bins others ate grass. We sought food from the fighters but they refused to give it to us."

Some 28 people have died of starvation in the city since December 1 including five on Sunday alone according to Doctors Without Borders known by its French acronym MSF.

The United Nations said it has asked the Syrian regime and opposition to allow 400 people many starved and malnourished to be airlifted out of Madaya for urgent medical attention.

"Around 400 are in need of being evacuated for life-saving medical attention" UN aid chief Stephen O'Brien told reporters after a Security Council meeting.

"They are in grave peril of losing their lives."

Heartbreaking

The head of the International Committee of the Red Cross's Syria delegation said the operation would likely last a few days.

Spokesman Pawel Krzysiek who reached Madaya with the trucks said the "first impression is really heartbreaking".

"We see a lot of people on the streets. Some are smiling and waving at us but many are just simply too weak with a very bleak expression too tired" he said in an audio message.

Assad gave permission for the deliveries on Thursday after an outpouring of international condemnation as footage of emaciated children in Madaya emerged on social media.

But Syria's envoy to the UN dismissed reports of civilians dying as fabrications accusing "terrorists" inside the town of stealing supplies.

Ambassador Bashar Jaafari said the reports were aimed at "demonising" the Assad regime and "torpedoing" peace talks later this month.

"Actually there was no starvation in Madaya" he told reporters. "The Syrian government is not and will not exert any policy of starvation on its own people."

Fifty trucks bearing the Red Crescent symbol were on their way to Madaya and 21 heading to Fuaa and Kafraya which are home to 20000 people the ICRC said.

The three towns along with rebel-held Zabadani were part of a landmark six-month deal reached in September to allow humanitarian assistance.

A first aid delivery went ahead in October and in December some 450 fighters and civilians were evacuated from Zabadani Fuaa and Kafraya.
