Around 400 people should be urgently evacuated from the besieged Syrian town of Madaya to receive medical treatment, UN diplomats have said.
Around 35,000 people are trapped in the town and had not received supplies since October until a an aid convoy arrived on Monday.
The World Health Organisation is seeking permission from the Syrian government to send mobile clinics and medical teams to the besieged Syrian town of Madaya, where hundreds of people are suffering the effects of starvation.
A WHO official in Damascus told Reuters that the agency has a list of 300-400 people who need "special medical care" inside the city.
A door-to-door assessment programme is urgently needed in Madaya, he said, to make sure the malnourished get immediate medical care and possible evacuation.
At least 50 trucks are taking food and medical supplies to 35,000 people trapped in Madaya which had been cut off from help for months.
An aid convoy intended for starving locals in a besieged Syrian village is due to set off on Monday, amid calls for the world to do more.
Shocking images from Syria shine a light on a cruel, medieval form of torture being inflicted on citizens - starvation, writes Rageh Omaar.
