Ukraine questions Russia's commitment to peace after Moscow failed to send its negotiation proposals to Kyiv before the meeting.

Ukraine has carried out large-scale drone strikes against several air bases deep inside Russia, destroying multiple combat planes, according to the Ukrainian Security Service (SBU).

With 41 military aircraft impacted, the Ukrainian drone attack was described by some commentators as Russia's "Pearl Harbor." The attack on Pearl Harbor in December 1941 was a surprise air raid by Japan on the U.S. during World War II. Kyiv's assault follows ground advances by Moscow troops in recent days in Ukraine's Sumy border region.
