Planned concerts in Poland by Pink Floyd co-founder Roger Waters have been canceled in the wake of his controversial statements on Ukraine, the organizers said on Sunday. 

Waters had been due to perform in Krakow next April before Polish media reported on a letter he wrote to Ukraine's first lady Olena Zelenska blaming “extreme nationalists” in Ukraine for having “set your country on the path to this disastrous war.”

Waters, 79, also criticized the West for supplying Ukraine with arms, provoking a fierce backlash.​​​​​​​

“Live Nation Polska and Tauron Arena Krakow have cancelled Roger Waters' concert,” organizers said in a statement on the venue's website. They gave no further details.

Some 6 million Ukrainian refuges have crossed over to Poland – a fellow former Eastern bloc country bordering Russia – since Moscow launched the war on Feb. 24.

Waters is famous for such Pink Floyd albums as The Dark Side of the Moon and The Wall.
