New Delhi, Apr 13 (IANS): President Ram Nath Kovind and Prime Minister Narendra Modi on Saturday paid tributes to the martyrs of Jallianwala Bagh massacre.

"A 100 years ago today, our beloved freedom fighters were martyred at Jallianwala Bagh. A horrific massacre, a stain on civilisation, that day of sacrifice can never be forgotten by India," Kovind tweeted.

"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," Modi said.

Saturday marks the 100th anniversary of the bloodbath, when British forces led by Brigadier General Reginald Dyer opened fire on hundreds of unarmed, innocent Indians, including women and children, who were protesting peacefully against the oppressive Rowlatt Act of the British government.

The massacre, on April 13, 1919, is one of the darkest chapters of India's freedom struggle against the British occupation.
