Looking inside Homs, central battlefield of Syria’s war

Syria’s civil war has killed more than 140,000 people. The city of Homs, once seen as the capital of the revolution, is now mostly controlled by government forces. Attack and starvation drove scores of rebels to flee or surrender, while the UN evacuated civilians in February. And yet, life goes on for some inhabitants.
