President Ram Nath Kovind and Prime Minister Narendra Modi on Saturday paid tributes to those who lost their lives in the Jallianwala Bagh massacre that took place on this day 100 years ago.

"Today, when we observe 100 years of the horrific Jallianwala Bagh massacre, India pays tributes to all those martyred on that fateful day. Their valour and sacrifice will never be forgotten. Their memory inspires us to work even harder to build an India they would be proud of," the Prime Minister wrote on Twitter.

The massacre took place on 13 April 1919 when troops of the British Indian Army under the command of Colonel Reginald Dyer fired machine guns into a crowd of unarmed protesters and pilgrims who had gathered in Jallianwala Bagh in Punjab's Amritsar on the occasion of Baisakhi.

The crowd had assembled peacefully at the venue to condemn the arrest of two national leaders -- Satya Pal and Saifuddin Kitchlew -- when they were fired at indiscriminately by General Dyer and his men.

According to British government records, 379 people including men, women, and children were killed while 1,200 were wounded in the firing. Other sources place the number of dead at well over 1,000.

Hundred years on, the United Kingdom is yet to give a full apology for the gruesome attack on unarmed protesters in Amritsar in 1919.

However, British Prime Minister Theresa May had recently said that the United Kingdom "deeply regrets" the 1919 massacre and called it a "shameful scar" on the British-Indian history.

"The tragedy of Jallianwalla Bagh in 1919 is a shameful scar on the British-Indian history. As her Majesty, the Queen said before visiting Jallianwala Bagh 1997, it is a distressing example of our past history with India. We deeply regret what happened and the suffering caused," May had said at the British Parliament earlier this week.
