While the world was gripped by the crisis over Syria’s chemical weapons and the West stepped towards and then back from brink of military intervention, a letter reached us from a doctor working in the city of Homs.

It was a disturbing dispatch from his own front line – a makeshift medical centre somehow still functioning in the shattered rebel streets of the Old City; streets that have been under siege by government forces for 500 days.
Here’s a little of what Dr Mosab wrote:
Dr Mosab made us this video too.
His is a world of trenches and tunnels through which they rush patients to avoid snipers, of out-of-date medicine, of operating theatres without fresh, clean water, of teenage boys who act as assistants.
To watch is to admire the persistence of humanity amid so much inhumanity, and then to wonder how long can they continue.
For there are now countless Syrians who are beyond help; beyond the reach of aid agencies.
This week, the Red Cross reported that the Syrian government is preventing it from delivering medical supplies to rebel areas.
One disfiguring feature of an ugly war has been the practice of both regime and rebels to target medical centres and health workers.
According to the World Health Organisation, a third of Syrian hospitals have been destroyed and a further twenty per cent severely damaged, while an estimated 15,000 doctors have been forced to flee abroad according to the Council on Foreign Relations.
Dr Mosab ends his letter with a simple appeal to the international community: "We are waiting for your help."
But no one can tell when that help will arrive, or indeed whether it will arrive at all.
