Amnesty International has accused US authorities of using artificial intelligence tools such as Palantir and Babel Street to monitor immigrants and target non-citizens at demonstrations supporting Palestinians, AFP reports.

A review of documents, including Department of Homeland Security public records, showed that software provided by the AI firms enables mass surveillance and assessment of people, often to target those not from the United States, according to Amnesty International.

“The US government is deploying invasive AI-powered technologies within a context of a mass deportation agenda and crackdown on pro-Palestine expression, leading to a host of human rights violations,” said Erika Guevara-Rosas of the rights group.

“Systems like Babel X and Immigration OS (from Palantir) play a key role in the US administration’s ability to carry out its repressive tactics,” said Guevara-Rosas.
