The Islamic Revolutionary Guard Corps (IRGC), a branch of Iran’s armed forces, has threatened to target US tech companies’ operations in the Middle East. It told employees of 18 companies — including Apple, Google, Meta and NVIDIA — “to leave their workplaces immediately to save their lives,” as CBS News reported. Those living close to the companies’ facilities in the region were instructed to evacuate immediately as well. Microsoft, Oracle, Tesla, HP, Intel, Palantir, Boeing, Dell, Cisco and IBM are also among the companies that the IRGC named.

“Since the main element in designing and tracking terror targets are American [information and communications technology] and AI companies, in response to this terrorist operation, from now on the main institutions effective in terrorist operations will be our legitimate targets,” the IRGC said in a statement. The military force warned it will start targeting the companies on Wednesday evening if more Iranian leaders are killed.

Iran previously pledged to attack companies and banks tied to the US and Israel, though the warning it issued on Tuesday had a specific deadline. Earlier this month, Iranian drones struck Amazon data centers in Bahrain and the United Arab Emirates, disrupting Amazon Web Services operations in the region.

The US reportedly used Anthropic’s AI in its initial airstrikes against Iran at the onset of the war in late February. Israel has been using a new AI platform of its own to help it track the movements of Iranian officials.
