Security crackdown on Sikh separatists re-ignites tensions with India's government

A large-scale police operation in the Indian state of Punjab has come to an end with the arrest of a Sikh preacher accused of encouraging separatism. The arrest of Amritpal Singh and several of his supporters on national security grounds reignited decades-old tensions between the Indian government and some in the Sikh community, and led to protests around the world.
