Ukraine suspected of launching drone attack on Kremlin, says US report.

US officials believe that Ukraine was likely behind the recent drone attack on the Kremlin, which Russia claims was an assassination attempt on President Vladimir Putin. The attack has raised concerns for the Biden administration, which has supplied Ukraine with military aid but fears that Russia could retaliate and expand the conflict beyond Ukraine's borders. While Ukrainian officials deny involvement, some intelligence experts believe it could have been a Russian false-flag operation. The Biden administration has cautioned Ukraine against conducting attacks inside Russia and publicly denied supporting the use of American military equipment for attacks beyond Ukraine.
