After maintaining a low profile for days over the agitation by the oustees in the Narmada valley, the Gujarat government on Thursday challenged the Narmada Bachao Andolan's claim that several villages would be submerged during this monsoon due to the backwater effect of the Sardar Sarover dam. Meanwhile, the second batch of NBA activists started their satyagraha in Domkhedi village in Maharashtra on Thursday following the arrest of Medha Patkar and 61 other NBA activists by the Maharashtra police after the hut in which they were staging the protest was submerged. But the dharna at Jalsindhi in Madhya Pradesh continued while the water was flowing a few feet below the satyagraha site.
