In this photo taken Tuesday, July 13, 2010, people gather around damaged houses after the flooding in Xiaohe, southwest China's Yunnan Province. Landslides slammed into three mountain hamlets in western China early Tuesday, killing 17 people and leaving 44 missing, while crews drained a fast-rising reservoir in another part of the country following heavy rains. The landslides swept through three different areas before dawn, state media said. In the worst-hit town of Xiaohe in Yunnan province, four died and rescuers were searching for 42 others, the official provincial newspaper Yunnan Daily reported on its website. (AP Photo/Xinhua)
