VANCOUVER - It's been 25 years since the bombing of Air India Flight 182, which left Montreal for Bombay with 329 people on board.

Today, memorials in several cities including Toronto, Ottawa and Vancouver will honour the victims of the bomb placed inside a suitcase.

The plane blew up over the Atlantic Ocean near Ireland on June 23, 1985, the same day a bomb meant for another Air India plane exploded, killing two baggage handlers in Tokyo.

Andre Gerolymatos, a terrorism expert at Simon Fraser University in Burnaby, BC, says the Vancouver memorial may be more muted because people are afraid to attend a public event in the city where the bombing plot was hatched.

Gerolymatos says even the general public may not attend the memorials because they don't consider the victims to be Canadian after then-prime minister Brian Mulroney's much-criticized offer of condolences to the Indian government.

Only one man has been convicted of supplying bomb parts in both explosions and two other B-C men were acquitted of all charges in March 2005.
