The northeast Indian state of Assam is threatened with serious flood, one month after the northern state of Uttarakhand was partially ravaged by water from an early monsoon season, said local officials Saturday. The Brahmaputra river in northeast India and its tributaries are flowing above the danger level across Assam, affecting over 100,000, the Press Trust of India quoted officials as saying in the state capital Guwahati. The Dhemaji district of the state has been worst-hit as incessant rainfall in the state\'s upper reaches have raised the water level of the Brahmaputra throughout the state. The flood has also hit the habitats of the one-horn rhinoceros at a national reserve park in upper Assam and a wildlife sanctuary in lower Assam, said the report. Some roads and bridges have also been damaged while at least one embankment has been breached by water. Authorities have set up five relief camps to provide relief materials and shelter to the affected people and those made homeless by flood. Hundreds have been confirmed killed while thousands remain missing in last month\'s flood in Uttarakhand state.
