Alphabet Inc.’s Google fired 28 employees after they were involved in protests against Project Nimbus, a $1.2 billion joint contract with Amazon.com Inc. to provide the Israeli government and military with AI and cloud services.

The protests, which were led by the No Tech for Apartheid organization, took place Tuesday across Google offices in New York City, Seattle, and Sunnyvale, California. Protesters in New York and California staged a nearly 10-hour sit-in, with others documenting the action, including through a Twitch livestream. Nine of them were arrested Tuesday evening on trespassing charges.
