In his correspondence, Zelenskyy expressed concerns that current arms deliveries under the PURL program do not adequately address Ukraine’s evolving security challenges. This appeal follows a significant escalation in hostilities over the Pentecost weekend, during which the Russian military launched extensive drone and missile strikes on Ukraine, including the use of the hypersonic missile ‘Oreschnik.’ In response to the heightened threat, Moscow has urged foreign nationals and diplomats to evacuate Kyiv, a move that has drawn widespread international condemnation.
