An ex-Al Jazeera America network staffer was canned after complaining that his boss was a sexist in the newsroom and went on “anti-American and anti-Semitic” rants about how “whoever supports Israel should die a fiery death in hell,” a new lawsuit charges.

Matthew Luke, who worked as the director of media and archive management, says in his Manhattan Supreme Court suit, that his boss, Osman Mahmud, displayed “overt misogynistic behavior and bias against women” by removing them from projects they were previously assigned to and excluding others from emails and meetings.

He is seeking $15 million from the news channel and Mahmud.

The boss’ unsavory behavior is part of ongoing efforts by execs at the Qatar-owned news channel to sideline women there — and put Arab Muslim men in charge instead, the suit alleges.

In February, Mahmud was promoted “because of his religion, nationality” and connections to top brass at AJA’s parent network Al Jazeera from a rank-and-file video editor to senior vice president of broadcast operations.

His “offensive and discriminatory behavior” was no secret in the newsroom but at a meeting last December, Mahmud’s bosses said “they had no choice but to accept and deal” with it because he was “so well-connected within the company,” the suit said.

In one instance, according to Luke, Mahmud instructed him to exclude two women from an email about a project they were working on and swap them out for a male employee.

“…There was no non-discriminatory reason to remove them from the project,” Luke said in the suit. “The reason that Mr. Mahmud insisted on removing them from the project was that they are female.”

Mahmud also made openly anti-Semitic and anti-American statements, the suit claims, citing one instance where he allegedly said, “Whoever supports Israel should die a fiery death in hell.”

Days later, Luke went to file a complaint with a human resources director — who “candidly stated [to Luke] that he had heard similar complaints from others regarding Mr. Mahmud” — but he learned that Mahmud had filed his own complaint about a previous disagreement, the suit says.

“Mr. Luke believed that [they] had both long moved past said disagreement,” the suit says.

Luke was eventually fired because he “did not fit into the company culture,” he says the company told him.

The lawsuit comes a week after The Post reported that staffers at the cable outfit are fuming over recent blood-letting and a shift in direction under CEO Ehab Al Shihabi.

Seven employees at the struggling outlet were laid off earlier this month. Sources told The Post Tuesday that head of communications Dawn Bridges and head of human resources Diana Lee have also resigned.

AJA and Mahmud didn’t return messages seeking comment.

“When Mr. Luke … reported the biased and discriminatory conduct of a high-level newsroom executive, the response was to circle the wagons and fire the messenger,” his attorney Jeffrey Kimmel said.

“One would expect more from an organization whose mission statement is ‘to be recognized as the world’s leading and most trusted media network.’”
