Iranian authorities arrested four individuals, including two foreign nationals, in the country’s northwestern region on Sunday. According to the Tasnim News Agency, the detainees are accused of being connected to a “U.S. and Israel-linked intelligence network.” They also face charges of importing satellite internet equipment similar to Starlink, which is considered a punishable offense in Iran.

The nationalities of the foreign suspects have not been disclosed. The arrests come amid heightened tensions following a joint attack on Iran by the United States and Israel on February 28, after which internet services across the country were reportedly shut down.

The report did not specify further details about the investigation or the current status of the detainees.
