Delhi Chief Minister Arvind Kejriwal expressed grief over the sudden demise of former president and eminent scientist A.P.J. Abdul Kalam on Monday evening.
"Very sad to hear that Dr APJ Abdul Kalam is no more. Nation has lost a real Bharat Ratna," he tweeted.
Kalam was admitted to Bethany Hospital in Shillong in a critical condition after he collapsed at the Indian Institute of Management-Shillong while delivering a lecture to the students of the B-school.
