Canada-India tension: India rejects links to Sikh leader's death

India has issued a travel advisory for its citizens in Canada, warning them to exercise caution.

It follows the Canadian government's announcement that it had credible evidence that India was behind the killing of a prominent Sikh activist in British Columbia in June. India calls the allegations “absurd”.
