<pChinese emergency services said Thursday that about 6,000 people were evacuated after a landslide in Tibet blocked the flow of one of the region's key rivers, creating a lake that could endanger downstream areas in India.
<pThe collapse Wednesday morning of a cliff in the deep valley through which the river flows created a dam-like barrier on the Yarlung Tsangpo, the headwater of India's Brahmaputra River, the local emergency response bureau said in a report carried by state media.
<pThe landslide struck near a village in Menling County and water in the lake had risen to a height of 40 meters (130 feet) by Thursday, the bureau said.
<pNo deaths or injuries were reported and the bureau said China has been keeping India updated on the blockage.
<pAuthorities in northeastern India issued an alert warning villagers in the East Siang district of Arunachal Pradesh, the state bordering China's Tibet region, not to venture near the river.
<pDistrict magistrate Tamiyo Tatak said water levels in the river had fallen drastically and once the blockage was cleared in China, water might suddenly rush downstream, causing a disaster in India.
<pIn June 2000, a sudden high discharge of water from the Yarlung Tsangbo caused extensive damage in Arunachal Pradesh and other downstream areas in India.
<pWith its towering peaks and glaciers, Tibet is the source of numerous Asian rivers, adding to China's strategic influence over its southern neighbors. Fast-rising temperatures have caused those glaciers to melt at an increasing pace, throwing a shadow over future water resources for China and other Asian nations.
