The RCMP, Peel police and Canadian Security Intelligence Service (CSIS) agents are trying to trace the locally based threatening call, but are unsure if it was made from a pay or cellphone.
Last week's attack threat come three moths after a Croatian man made a bomb threat near an El Al ticket counter, and one month after a St. Catharines, Ont., man was charged for phoning in a bomb threat to Pearson.
