The Election Commission of India has asked AAP convener Arvind Kejriwal to provide factual evidence to substantiate his serious allegations that the river Yamuna was poisoned by the neighbouring Haryana state; the nature and extent of the chemical used for the poisoning Yamuna that would have killed the people in large numbers resulting into mass genocide; and that the engineers of Delhi Jal Board have actually detected and prevented it timely, much before it could mix with the waters of Yamuna in Delhi and caused genocide.
