Ukraine fears that Russia is preparing large-scale "terrorist attacks" against Ukraine. NATO warns that critical infrastructure in Europe may be threatened.

Russian presidential office claimed that Ukraine is behind a drone strike on the Kremlin overnight, which was averted. Russian President Vladimir Putin rejects the accusations from the Kremlin: "Of course, Ukraine has nothing to do with drone strikes against the Kremlin" "We are not attacking the Kremlin because, above all, it does not solve any military tasks," he said in a written comment.
