Poland's prime minister, Donald Tusk, appears to have hit back at U.S. officials after a heated social media exchange saw the country's foreign minister argue with U.S. Secretary of State Marco Rubio and SpaceX chief executive Elon Musk over Starlink access in Ukraine.

Radoslaw Sikorski suggested that Poland, which pays Ukraine’s Starlink costs to help it repel Russia’s invasion, might have to seek alternative suppliers if Elon Musk’s satellite network proves to be an 'unreliable provider.

The spat started Sunday when Musk responded to an X post that claimed he didn't call out Russia for being the aggressor in it war and only called out Ukraine.
