When six-week-old Zubair arrives at a clinic for malnourished children in Afghanistan, doctors initially give him only a few hours to live. And as he battles under a survival blanket his mother looks on -- her feelings swinging desperately between fear and hope. The Doctors Without Borders (MSF)-run facility in Herat, western Afghanistan's biggest city, seeks to help the community cope with a public health system on its last legs, hobbled by the withdrawal of donor aid. Since the Taliban overran Kabul in August, the facility has increased its capacity from 45 to 75 beds, and receives around 60 new patients each week. The UN's children's agency UNICEF estimates that some 3.2 million Afghan children under the age of five will suffer from malnutrition this winter. A million of them could die in the absence of intervention, it calculates. IMAGES AND SOUNDBITES ARRANGED IN SEQUENCES
