Lucknow, Jan 22(ANI): Stating that the 21st century belongs to India, because India is the youngest country of the world and youth are our strength and precious to us, Prime Minister Narendra Modi on Friday said it pained him a lot to know that a youth of the country, Rohith Vemula, was forced to commit suicide. Speaking at a convocation programme of Babasaheb Bhimrao Ambedkar University, PM Modi said that reasons will have its own place and politics its own, but truth is that Mother India has lost a son.
