India¡¯s external intelligence service is a feared foe in its neighborhood: Pakistan, Sri Lanka and Nepal have all accused it of political meddling and involvement with outlawed groups that have perpetrated acts of violence.

Now, Canadian Prime Minister Justin Trudeau¡¯s allegation last month that Indian government agents were involved in the June killing of Sikh separatist leader Hardeep Singh Nijjar in a Vancouver suburb has thrust Delhi¡¯s secretive Research and Analysis Wing (RAW) into the global spotlight.

India angrily denied the allegations and demanded that Canada ¡ª which expelled RAW¡¯s station chief ¡ª furnish evidence. Ottawa said it shared proof with allies, but will not release it publicly.
