Photos of a Syrian baby who lost an eye and suffered severe head injuries in a reported government attack have sparked a solidarity campaign on social media.
Karim, who is only two months old, was hurt when artillery shells struck a market in the rebel-held Eastern Ghouta area on the outskirts of Damascus on 29 October. His mother was killed in the incident.
Home to an estimated 400,000 people, towns and villages in the Eastern Ghouta have been under siege by government forces since 2013.
But despite the area being designated a "de-escalation zone", hostilities have intensified in recent weeks.
The International Committee of the Red Cross said on Monday that the situation in the area had reached a "critical point", with life "slowly becoming impossible".Image copyright AFP Image caption The Eastern Ghouta has been devastated by years of fighting
About 500 people are waiting to be evacuated for life-saving medical care. There are also severe shortages of food, fuel and medicines, and the cold weather threatens to worsen the hardship.

Images of Karim's injuries were first circulated in late November.

This is not the first time the plight of a baby has led to a widespread campaign on social media.
Earlier this year, a similar push campaign took place in Yemen, where users shared photos of themselves with one eye closed in solidarity with a young girl injured and orphaned in an air strike by a Saudi-led coalition battling the rebel Houthi movement.
