BJP leader Uma Bharti on Sunday said the Uttarakhand flood tragedy triggered by a glacier burst is a matter of concern as well as a warning. She added that as a minister she had spoken against any power project on the Ganga and its major tributaries. Uma Bharti was the minister of water resources during the first term of the Modi government. "When I was a minister, my ministry in its affidavit about the dams in Uttarakhand in the Himalayas had requested that it is a very sensitive region, and, therefore, power projects should not be built on the Ganges and its main tributaries," she tweeted.
