The overnight Ukrainian drone attack reached unprecedented scale, with Russian media reporting nearly 300 intercepted drones across 13 regions—the largest single assault to date. Moscow's airports suspended over 100 flights as 42 drones targeted the capital region alone.
Against this backdrop of escalation, diplomatic momentum accelerated rapidly. Foreign Minister Lavrov announced Russia would meet Ukraine on June 2 in Istanbul to exchange peace memorandums, following phone calls between negotiators Medinsky and Ukrainian Defense Minister Umerov. By afternoon, both sides had transmitted their draft ceasefire documents.
Lavrov briefed US Secretary of State Rubio on the Istanbul preparations, while Trump indicated readiness for a three-way meeting with Putin and Zelensky. The Kremlin framed Germany's long-range missile commitments to Ukraine as "war provocation," with Lavrov claiming Berlin was "sliding toward collapse." Russian media reported threats against negotiator Medinsky's family from Ukrainian sources.
