OTTAWA (AFP) - A Canadian domestic Westjet flight skidded off the end of a runway at the Montreal airport during a thunderstorm on Friday but no injuries were reported.

Televised images showed the mid-sized passenger jet, which had arrived from Toronto, surrounded by emergency vehicles on a patch of grass at the end of the runway.

Its landing gear appeared to be stuck in mud, but intact.

Montreal airport spokesman Marie-Claude Desgagnes told AFP there were "no injuries" and there was "no fire aboard about the jetliner". Flights in and out of Montreal are not expected to be delayed as a result of the accident, she added.

Westjet spokesman Richard Bartrem told public broadcaster CBC the plane landed in a "heavy rainstorm". There was a lot of water pooled on the tarmac at the time that may have contributed to the plane skidding, he said.
