In Afghanistan, avalanches and freezing weather have killed more than 20 people. Officials said that rescue work is on to save scores still trapped under the snow. The avalanches, which followed three days of heavy snow, destroyed homes and blocked roads in central and northeastern provinces. In northeastern Badakhshan province at least 18 people, including three women and two children, were killed when avalanches hit their houses overnight. Five people were killed by avalanches in the Balkhab district of Sari Pul province in northern Afghanistan and at least 70 people trapped under the snow were being rescued. <br/><br/>Freezing weather also killed at least two people and over 100 animals in western Badghis province. Deadly avalanches are common in Afghanistan's mountainous areas in winter and rescue efforts are frequently hampered by lack of equipment.
