After claiming to have ended Ukraine's incursion into Kursk — with North Korean help — Russia says it is ready to hold peace talks with Kyiv. But President Trump has cast doubt on Putin's remarks and theatened sanctions.

Russian President Vladimir Putin has claimed that his country has regained control of Kursk, the border region where Ukraine launched a surprise offensive last year, though Ukraine’s army says fighting continues.

All Ukrainian troops have been forced from Russia’s Kursk region, Kremlin spokesperson Dmitry Peskov said Saturday. Ukrainian officials have not commented on the claim.
