Poland's Prime Minister Donald Tusk on Monday rebuked Polish opposition politicians for supporting verbal attacks made by American politicians against Polish Foreign Minister Radoslaw Sikorski over the weekend.

The feud between American and Polish officials began with the X post by American billionaire Elon Musk on Sunday, reports AA.

The head of the US Department of Government Efficiency (DOGE) and owner of SpaceX, which provides internet via Starlink satellites, Musk said: "My Starlink system is the backbone of the Ukrainian military. If we turn it off, the entire Ukrainian front in the ongoing Moscow-Kiev war will collapse."

Sikorski responded: "Starlink for Ukraine is financed by the Polish Ministry of Digital Affairs at a cost of about $50 million per year. Putting aside the ethics of threatening the victim of aggression, if SpaceX turns out to be an unreliable supplier, we will be forced to look for other suppliers.", reports KosovaPress.

Politicians from the opposition party came out in support of the US administration, after Musk told Sikorsky in X: "Shut up, little man. You pay a small fraction of the costs. And there is no replacement for Starlink."

Lawmaker Michal Wojcik called for the resignation of the Polish government, while Pawel Jablonski declared that "for the good of Polish diplomacy, someone should take down Sikorski's Twitter."

Member of the European Parliament Arkadiusz Mularczyk wrote on X: "We apologize to Sikorski."

Tusk then said in X: "By attacking Sikorski, who calmly explains to politicians from another country about the Polish national interest, (the opposition) PiS (Law and Justice party) is losing the last remnants of its national dignity. It is politically and morally bankrupt."

Meanwhile, US Secretary of State Marco Rubio, in a tweet, accused Sikorsky of "making things up" and said: "Nobody threatened to cut Ukraine off from Starlink. And thank goodness, without Starlink, Ukraine would have lost this war a long time ago, and the Russians would now be on the border with Poland," reports KosovaPress.

Recently, talks between Eutelsat -- one of Europe's largest satellite operators -- and the EU have reportedly intensified, and the satellite operator could eventually replace the US network of communications terminals in Ukraine.
