New Delhi/IBNS, Jan. 28 -- The Delhi Jal Board has rejected Aam Aadmi Party (AAP) supremo Arvind Kejriwal's claim that the Haryana government has poisoned the Yamuna river, media reports said.

Kejriwal, a former Delhi chief minister, made the startling claim in the run up to the assembly elections in Delhi.

The AAP supremo accused the Bharatiya Janata Party (BJP) government in Haryana of polluting raw water supply to the national capital.

Countering the allegations, Haryana chief minister Nayab Saini called Kejriwal's comments "cheap politics".

In a counter-attack, Kejriwal said he won't budge down in raising the issue as it would affect the residents of Delhi....
