Salman Khan has expressed his deep regret on not meeting former President APJ Abdul Kalam, saying he should have made the effort to see him.

Kalam, who served as the 11th President from 2002 to 2007 and came to be known as 'People's President', died on Monday after he collapsed during a lecture at IIM Shillong on Monday. He was 83.

Salman said it is his loss that he could not meet Kalam. "When your heart says you should meet someone, don't delay. I always wanted to meet Kalam saab and I should have made the effort. My loss," the 49-year-old 'Bajrangi Bhaijaan' star posted on Twitter.

In a series of tweets, Salman also condoled Kalam's death and called him a "true inspiration". "I will miss Kalam saab. India will miss him," he wrote. "Kalam saab was an amazing teacher and in his last tweet he said he is on his way to IIM... as scientist and as President, Kalam saab was a true inspiration for many generations of Indians," Salman posted.
