The unprecedented rains that battered Bihar in the last three days of September has cost 55 lives -- a jump from the last known figure of 42 -- the state government said today. Even two days after the rain stopped, the water level in Patna is yet to go down, triggering fears of epidemic. Today, Chief Minister Nitish Kumar admitted that the water pumps in the city are not working and said he would take the urban development ministry to task once the crisis is over - a remark seen as a dig at ally BJP, which have been openly critical of him over the waterlogging.
