Nearly 500 drones and 20 missiles of various types were launched by Russia at Ukraine overnight, marking the biggest barrage of the war, Kyiv said. 

On Monday, Ukraine’s air force said its air defenses were able to destroy 277 of the 479 drones launched in the darkness and 19 missiles mid-flight. Kyiv claims only 10 drones of missiles hit their target and just one person was injured.

The bombardment targeted mainly central and western areas of Ukraine, they said.

Russia’s aerial attacks usually start late in the evening and end in the morning, as drones are harder to spot in the dark.

“We have seen and heard a hundred different excuses, justifications and so on, but it is difficult to view them as credible,” Kremlin spokesman Dmitry Peskov told reporters, according to Reuters. “The Russian side remains ready to implement the agreements reached in Istanbul.”

The exchanges were agreed to during a second round of direct peace talks in Istanbul on June 2 and are meant to see a new prisoner of war swap of at least 1,200 people – focusing on the youngest and most severely wounded – as well as the repatriation of thousands of bodies of those killed in the war.

The return of prisoners of war and the return of the bodies of the dead is one of the few things the two sides have been able to agree on, even as their broader negotiations have failed to get close to ending the war, now in its fourth year.
