The Election Commission on Thursday asked AAP convenor Arvind Kejriwal not to mix the issue of increased ammonia in Yamuna with his allegation of river poisoning, and gave him an opportunity to explain his charges against the Haryana government, reported news agency PTI.

Not satisfied with Kejriwal’s reply, the EC asked the former chief minister to provide factual evidence with specific and pointed response to the type, quantity, nature and manner of poisoning of Yamuna.
