Google has fired 28 employees in the aftermath of protests over technology that the internet company is supplying the Israeli government amid the Gaza war, further escalating tensions surrounding a hot-button deal.

The firings confirmed by Google late Wednesday came a day after nine employees were arrested during sit-in protests at offices in New York and Sunnyvale, California, after the company called police.

The dissent roiling Google centers on “Project Nimbus,” a $1.2 billion contract signed in 2021 that calls upon Google and Amazon to provide the Israeli government with cloud computing and artificial intelligence services.

The protests are being organized primarily by a group called No Tech For Apartheid. Google says Nimbus isn’t being deployed in weaponry or intelligence gathering.
