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.

By making harsh, uncompromising demands in peace talks with Ukraine while continuing to pummel it with waves of missiles and drones, Russian President Vladimir Putin is sending a clear message: He will only accept a settlement on his terms and will keep fighting until they’re met.

Russia may find itself in a disadvantageous position in the eyes of the United States if it fails to show flexibility in peace negotiations with Ukraine, states Turkish Foreign Minister Hakan Fidan, according to Anadolu.
