Heavy monsoon rains triggered floods in India's north-eastern state of Assam on Saturday, displacing at least 50,000 people in the region. No casualties were reported. A government spokesman told the IANS news agency that the Singora river had inundated at least 40 villages in the Lakhimpur district, 360 kilometres north-east of state capital Guwahati. The floodwaters from Singora - a tributary of the Brahmaputra, among Asia's largest rivers - forced villagers from low-lying areas to take shelter on raised platforms and railway tracks. "There has been a breach of about 20 to 30 metres in two embankments and that led to floodwaters entering human settlements," a district official told the news agency.
