The Sikh immigrant from India was convicted of making bombs that were stuffed into luggage and planted on two planes leaving Vancouver, and of lying in court to cover for his co-accused.
One bomb tore apart Air India Flight 182 – Kanishka – as it neared the coast of Ireland, killing all 329 people aboard, including entire families.
The second exploded at Japan’s Narita airport, killing two baggage handlers as they transferred cargo to another Air India plane.
The blasts followed a crackdown on Sikhs militants, and those behind it were allegedly seeking revenge for the Golden Temple operation.
