Air Canada indicated that one of its pilots  posted "unacceptable posts" about Israel following the deadly attacks on Gaza over the weekend, and that he no longer works there.

On Tuesday afternoon, the group StopAntisemitism.org shared posts on Instagram allegedly made by the man, whom they identified as a pilot onboard the carrier.

The posts allegedly show the man wearing Palestinian colors - over his flight suit in one photo - holding signs that read "Israel Hitler is proud of you" and showing the Israeli flag thrown in a trash bin beneath the caption "Keep the world clean". 

On Saturday, the Islamic resistance movement (Hamas) launched surprise incursions across the Israeli border from Gaza, resulting in civilian deaths and escalating the conflict that has claimed more than 2,200 lives.

By Wednesday, Israel had intensified its retaliatory operations against Hamas and launched more rockets at the Gaza Strip, amid growing fears of a humanitarian catastrophe as bombardments leveled neighborhoods, while the blockade imposed on the isolated coastal area has prevented electricity, food, water, and fuel.

Another alleged post by the pilot promotes a pro-Palestinian protest in Montreal on Sunday that includes a vulgar word against Israel and describes it as "burning in hell".

In a post on Tuesday on X, formerly known as Twitter, Air Canada stated that the flight officer had been removed from service the previous day, when it became aware of "the unacceptable posts made by an Air Canada pilot".

In an update on Wednesday, the airline said that the pilot in question no longer works for Air Canada, "following the process that began on Monday".

The Canadian press has not disclosed the man's name after being unable to reach him to verify the contents of the posts. His accounts on Instagram and LinkedIn appear to have been deleted.

The Airline Pilots Association, which represents more than 5,000 pilots at Air Canada, said it is aware of the situation.

"We condemn all acts of violence and hatred and any promotion of them. The Air Canada unit of the union said in a statement sent via email: “We strongly expect all our members to adhere to this principle and our professional ethics rules.”
