Russia alleges Ukraine launched 91 long-range drones towards President Vladimir Putin's residence in the Novgorod Region on December 28-29, claiming all were destroyed by air defense systems. Russian Foreign Minister Sergey Lavrov stated this 'terrorist attack' would not go unanswered and could affect Russia's negotiating position, though not lead to withdrawal from talks. Ukraine's Foreign Minister Andrii Sybiha rejected the claims, accusing Moscow of fabricating the incident and spreading disinformation, noting Russia's failure to provide credible evidence.
