CHONGQING, June 29 (Xinhua) -- One person was killed and two others are missing Monday after a rainstorm hit southwest China's Chongqing Municipality causing landslides and a slag heap to collapse.

    Rescuers were digging through the slag heap in Hechuan District of Chongqing on Monday afternoon, searching for two men who were buried during the rainstorm, said officials from the district government.

    Another person, whose identity is not known yet, was killed in a landslide in Qijiang County, according to the municipal headquarters of flood control.

    In another landslide, more than 100 tons of rocks and soil fell onto an expressway and covered a 30-meter section. No one was in the area when the landslide took place Sunday night, the headquarters said.

    The rainstorm began to ravage Chongqing Sunday and has led to temporary evacuation of thousands of people from their homes, said Liu De, head of the Chongqing observatory. A village named Tiefeng was cut off power, roads and communication by the rainstorm.

    Water levels in the rivers of Yangtze and Jialing began to rise Monday morning and the Chongqing city was expected to brace for a flood peak early Wednesday morning, Liu said.
