Dead fish found in the Yamuna have triggered a political confrontation in Delhi, just days ahead of Chhath Puja. Delhi Minister Parvesh Verma has alleged that some people deliberately dumped the fish to spoil the festive atmosphere and says an FIR has been ordered. The Aam Aadmi Party has questioned the government's claims, pointing instead to the river's pollution and asking why the alleged dumping does not figure in the complaint. Both sides have traded accusations as the controversy grows.
