NATO Secretary-General Mark Rutte said Wednesday he spoke with Ukrainian President Volodymyr Zelenskyy about accelerating the delivery of additional air defense systems following a fresh wave of Russian missile and drone attacks across Ukraine.

The discussions come as Moscow intensifies its long-range bombardments against Ukrainian cities and critical infrastructure, pressing NATO allies to bolster Ukraine's defensive capabilities.

"Spoke with Zelenskyy about the latest horrific Russian missile and drone strikes on Ukraine’s cities," Rutte said in a statement posted to the US social media platform X. "I am discussing with Allies how we can continue to get Ukraine the air defences they urgently need."

Zelenskyy also said he discussed efforts with Rutte.

"Mark is well-informed about the threats, and we have coordinated our efforts regarding countries that possess the necessary ⁠missiles ⁠and the capability to help," Zelenskyy wrote on X.
