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.

The assault happened not long after President Trump pledged to send more military aid to Ukraine. CBS News New York's Natalie Brand reports.

Ukraine's military said it eliminated hundreds of Russian drones overnight after Moscow launched a massive aerial attack targeting the northwestern city of Lutsk.
