Elon Musk’s satellite internet service Starlink is in use by the Russian army, Ukrainian military intelligence said on Sunday.

“The Main Directorate of Intelligence of the Ministry of Defense of Ukraine confirms the use of Starlink satellite communication systems by the Russian occupiers at the front,” it wrote on Telegram.

The intelligence service also posted a short conversation between what it says are Russian soldiers who mention the use of Starlink. “Radio interception of the invaders’ conversation shows that in order to establish access to the internet, Starlink terminals were installed,” according to the post.
