REDMOND, Wash. (AP) -- A pro-Palestinian protester interrupted the keynote event of Microsoft's 50th anniversary celebration Friday, the latest backlash over the tech industry's work to supply artificial intelligence technology to the Israeli military.

The protest happened as Microsoft AI CEO Mustafa Suleyman was presenting product updates and a long-term vision for the company's AI assistant product, Copilot, to an audience that included Microsoft co-founder Bill Gates and former CEO Steve Ballmer.

"Mustafa, shame on you," shouted a woman in the audience. "You claim that you care about using AI for good but Microsoft sells AI weapons to the Israeli military."

She said 50,000 people have died and described it as a genocide.

"Thank you for your protest, I hear you," Suleyman said. The protester continued, shouting that he and "all of Microsoft" had blood on their hands.

An investigation by The Associated Press revealed earlier this year that AI models from Microsoft and OpenAI had been used as part of an Israeli military program to select bombing targets during the recent wars in Gaza and Lebanon. The story also contained details of an errant Israeli airstrike in 2023 that struck a vehicle carrying members of a Lebanese family, killing three young girls and their grandmother.

In February, five Microsoft employees were ejected from a meeting with CEO Satya Nadella for protesting the contracts. While the February event was an internal meeting, Friday's protest was far more public -- a livestreamed showcase of the company's past and future.

"We provide many avenues for all voices to be heard," said a statement from the company Friday. "Importantly, we ask that this be done in a way that does not cause a business disruption. If that happens, we ask participants to relocate. We are committed to ensuring our business practices uphold the highest standards."

Microsoft declined to say whether it would take further action.
