At least one person has been killed after Russia launched its largest drone attack on Ukraine since the beginning of its invasion, Ukrainian officials said Wednesday, just hours after US President Donald Trump pledged more military support for Kyiv and accused his Russian counterpart Vladimir Putin of throwing “bullsh*t” over peace talks.

Kyiv is trying to blunt Russia’s grinding advance with a new generation of quadcopters steered by long coils of ultrathin and highly versatile wire.

President Trump said on Monday that the United States would send more weapons to Ukraine to help it fend off Russia’s invasion, arguing that Moscow’s recent assault on Ukrainian cities left him with little choice,

Following the Pentagon announcing a pause on weapons, the U.S. president said Ukraine must defend itself from Russia.
