Meanwhile, Russia has stated that Ukraine's latest attack against its territory marks a new phase of Western war against Moscow.

At the same time, Ukraine is struggling to hold back Russian advanced further south, around the city of Kurakhove, which has been surrounded from three sides for months. Earlier this week, Zelensky called the situation around Kurakhove “the most difficult area” of the frontline.

Ukraine said it destroyed nearly all the Kinzhal and Zirkon missiles that Russia fired in a massive weekend barrage.
