Cameron visits Amritsar massacre site
David Cameron has become the first serving UK prime minister to pay his respects at the scene of one of the bloodiest massacres in British history.
Mr Cameron is visiting Amritsar in the state of Punjab on Wednesday, at the end of a three-day trade trip to India.
This is where hundreds of people at a public meeting were shot dead by British troops in 1919. The BBC's Sanjoy Majumder explains.
