The two men charged in the deadliest terrorist attack on a commercial airliner prior to September 11 will learn their fate in a Canadian courtroom tomorrow as a judge delivers his verdict in the 1985 Air India bombings that killed 331 people.

Lawyers have made their final arguments in the murder trial of two Sikhs charged over the 1985 bombing of an Air India jumbo jet, ending one of the most exhaustive and expensive trials in Canadian history.

The two men accused of the Air India jumbo jet bombing that killed 329 people nearly 20 years ago were guilty beyond a reasonable doubt, Canadian prosecutors said.

Arrest warrants have been issued for a Sikh militant leader who led a separatist campaign in India from his London home.
