There was a threat of a rocket attack on an El Al jet landing in Toronto, says the The Globe and Mail.

A missile threat led to the diversion of an El Al flight from Toronto's Pearson airport to nearby Hamilton on Thursday, an Israeli source said Friday.

The flight, with 180 passengers aboard, let Toronto-bound passengers off in Hamilton before continuing to Los Angeles. The return flight to Israel on Friday also landed at Hamilton instead of Toronto.

Transport Minister David Collenette, speaking from Ottawa, said the plane was diverted again because El Al believed the threat against the plane continued.

He would not give details about that threat, but an Israeli source told Canadian Press that it involved a ground-to-air missile.

Four Canadian agencies are investigating the threat, but there was no indication of a real weapon.

Needless to say, this is disturbing news. Even if it isn't true, it'll rattle both Canadians and Americans.
