As the war in Syria enters its fifth year - with no signs of fighting coming to an end - millions are struggling to survive.
This week a series of strong storms blanketed much of the country in snow. Syrians living in towns and villages - besieged by government forces and their allies - are facing starvation.
The blockade of the town of Madaya near the Lebanese border, in particular, has become a focal issue for Syrian opposition leaders.
They told the UN envoy this week they won't take part in talks with the government until the siege there and in other areas is lifted.
So, what can be done to help the millions of desperate Syrians?
