Iran has officially protested to Norway over what it described as unauthorized Starlink satellite internet operations within its territory, Iranian state media reported on Monday.

Iran’s Foreign Ministry summoned the Norwegian ambassador to Tehran on Sunday and handed him a formal protest note.

Iranian officials accused the United States and Israel of using Starlink satellite systems to carry out “interfering actions” against Iran.

Tehran also accused Norway of failing to meet its obligations as the country responsible for the registration of Starlink’s satellite network with the International Telecommunication Union (ITU).

Iran claims decisions by the ITU’s Radio Regulations Board required Norway to take measures to prevent unauthorized Starlink transmissions in Iranian territory.

Iranian officials demanded immediate action from Oslo to halt what it described as Starlink activities, which they view as a direct violation of Iran’s national sovereignty and national security.

In March, Iranian authorities said they had arrested 30 people accused of spying for Israel and the US during the conflict. Iranian security forces also reported the confiscation of weapons as well as Starlink devices from them.

Starlink is a network of thousands of satellites and users require a special antenna with a router function to connect to the internet.

The system is banned in Iran but around 50,000 terminals are believed to have entered the country via smuggling routes, according to estimates.
