The High Court had directed Uttar Pradesh government to ensure that the water released from Narora dam reaches here and is not diverted on the way through lift canals.

Swami Hari Chaitanya Brahmachari, who has been agitating over the Ganga water issue, has threatened to take jal samadhi on Friday.

The swami, who led a march of saints from dandi swami camp to the bank of the Ganga on Thursday, is being persuaded by others to defer his threat.
