Ganga activist's death: Rahul Gandhi vows to take fight for clean river forward
Describing Agarwal as "the true son of mother Ganga", Gandhi said he gave away his life to save the river.
It is rivers like the Ganga that have made India, the Congress chief noted.
Agarwal, who began his hunger strike on June 22 demanding government measures to save the Ganga, died of a heart attack at the All India Institute of Medical Sciences in Rishikesh. The activist was admitted to hospital on Wednesday after he even gave up water.
