AMRITSAR, Nov 18: At least three people were killed and eight others injured in a grenade blast at a religious congregation in Amritsar’s Rajasansi village on Sunday, police said.

The government has been accused of covering up the full extent of the UK’s support for India’s bloody crackdown on Sikhs in 1984. A new report calls for a full inquiry into the role played by Margaret Thatcher’s government in the events leading up to a massacre in which hundreds, possibly thousands, of Sikhs and Indian soldiers died. In 2014 David Cameron ordered a review after the accidental release of secret documents revealed that a British SAS officer had been drafted in to advise the Indian authorities on removing armed Sikh militants from the Golden Temple at Amritsar, Sikhism’s holiest shrine.
