Five Sikhs were charged with conspiracy in Montreal for reportedly plotting to blow up an Air-India jetliner on a flight from New York to New Delhi. Canadian officials said the five were seized Friday in a series of raids in the Montreal area. They said warrants had been issued for three additional suspects. The Toronto Globe and Mail quoted sources as saying that the arrests involved a plan to plant a bomb aboard an Air-India Boeing 747 jumbo jet "in the next several days." The prosecutor in the case, Pierre Garon, would only say the investigation centered on suspicions of trouble aboard an aircraft. The five are all from Montreal.
