Russia launched its largest single drone strike against Ukraine just before a scheduled phone conversation between President Donald Trump and Vladimir Putin focused on ending the conflict.

On Sunday, Russia deployed a total of 273 explosive drones and decoys aimed at regions in Ukraine including Kyiv, Dnipropetrovsk, and Donetsk, as reported by Ukraine’s air force. Among these, 88 drones were intercepted and 128 likely lost due to electronic jamming.

Yuriy Ihnat, head of the air force’s communications department, informed the Associated Press that this was the largest drone attack since Russia’s comprehensive invasion began in February 2022.

It came after Trump said he would be “speaking, by telephone, to President Vladimir Putin of Russia on Monday, at 10:00 a.m.” regarding the war in Ukraine.

Vice President JD Vance and Secretary of State Marco Rubio also met with Zelenskyy in Rome Sunday for ongoing peace talks. 

“During our talks we discussed negotiations in Istanbul to where the Russians sent a low-level delegation of non-decision-makers. I reaffirmed that Ukraine is ready to be engaged in real diplomacy and underscored the importance of a full and unconditional ceasefire as soon as possible,” Zelenskyy shared on X regarding the meeting.  

“We have also touched upon the need for sanctions against Russia, bilateral trade, defense cooperation, battlefield situation and upcoming prisoners exchange. Pressure is needed against Russia until they are eager to stop the war. And, of course, we talked about our joint steps to achieve a just and durable peace,” he continued.

World leaders converged in Rome this weekend for Pope Leo XIV’s inaugural mass at the Vatican on Sunday, with Vance leading the U.S. delegation. Zelenskyy also attended the mass.
