Two villages of Ratua I block of Malda district are facing the threat of erosion after the water level of the Ganga reached the danger level Sunday morning, Block Development Officer Arjun Pal said.
Around half of the 1000 odd population of the two villages - Janjalitola and Naya Bilaimari - have taken shelter in neighbouring Bihar, the BDO said.
The two villages may be lost in the erosion of the river any moment and the villagers were provided with disaster management kits, he said.
Erosion has been taking place at a stretch of around 3 km in that area.
