Afghan children walk on mud at a refugee camp in Kabul February 1, 2005. The International Security Assistance Force (ISAF) has provided each of the 450 Afghan families about 14 tonnes of wood and a 5 kg can of cooking oil. A drop in temperatures of up to minus 18 degrees Celsius (0 degrees Fahrenheit) has killed at least five people recently. REUTERS/Ahmad Masood AM/JJ
