New Delhi:  Prime Minister Narendra Modi on Friday remembered freedom fighter Udham Singh on his martyrdom day.

“The valour of Shaheed Udham Singh remains etched in the memory of every Indian. I bow to this brave son of India on his martyrdom day,” he said in a tweet.

Born in 1899, Singh was hanged in London’s Pentonville Prison for assassinating then Punjab lieutenant governor Michael O’Dwyer to avenge the Jallianwala Bagh massacre on July 31, 1940.
