On 18 November 1998, the Canada-based Sikh journalist Tara Singh Hayer was gunned down by suspected Khalistani militants. The publisher of the "Indo-Canadian Times," a Canadian Sikh and once-vocal advocate of the armed struggle for Khalistan, he had criticised the bombing of Air India flight 182, and was to testify about a conversation he overheard concerning the bombing. On 24 January 1995, Tarsem Singh Purewal, editor of Britain's Punjabi-language weekly "Des Pardes", was killed as he was closing his office in Southall. There is speculation that the murder was related to Sikh extremism, which Purewal may have been investigating. Another theory is that he was killed in retaliation for revealing the identity of a young rape victim.
