Amazon.com Inc. has terminated Ahmed Shahrour, a 29-year-old Palestinian engineer, following his protests against the e-commerce giant's ties to the Israeli government.

Shahrour, employed by Amazon's Whole Foods Market unit, was dismissed on Monday for violations of company policy, including statements deemed to "threaten, intimidate, coerce or interfere with" senior leaders and colleagues, according to an internal email.

He was suspended last month after posting messages in corporate Slack channels criticizing Amazon’s contracts with Israel. Shahrour also staged protests and distributed fliers at Amazon’s Seattle headquarters.

“We don't tolerate discrimination, harassment, or threatening behavior or language of any kind in our workplace, and when any conduct of that nature is reported, we investigate it and take appropriate action based on our findings,” Amazon spokesperson Brad Glasser said in a statement.

Amazon, along with Alphabet Inc.’s Google, provides cloud-computing services to Israeli government and military entities under a contract called Project Nimbus. Both companies have faced protests from critics of Israel’s conduct during its war in Gaza, which ended with a ceasefire earlier this week.

Shahrour criticized the company in a note to colleagues, stating, “Amazon is not a neutral observer. We are active participants.”

He was also part of a group of seven current and former tech workers who occupied Microsoft President Brad Smith’s office in August, protesting Microsoft’s sales to Israel. The protesters were arrested and later released. Following the protests, Microsoft restricted the use of some software by an Israeli military unit.

Shahrour’s firing highlights growing tensions in the tech industry over ethical concerns surrounding contracts with governments involved in military conflicts.
