European diplomats have privately warned Moscow that NATO is prepared to respond to further airspace violations with full force, including shooting down Russian aircraft, according to officials familiar with the exchange cited by Bloomberg. A Russian diplomat conveyed to British, French, and German envoys in Moscow that recent Russian air incursions into Estonia were a direct response to Ukrainian attacks on Crimea. In parallel, Russian media reports indicate that a gasoline shortage is now beginning in the Moscow region, following similar reports of shortages, price hikes, and rationing in other Moscow-area cities due to Ukraine's ongoing drone campaign. Separately, U.S. Secretary of State Marco Rubio has reportedly accepted an invitation from Ukrainian Foreign Minister Andrii Sybiha to visit Ukraine. These developments occur as NATO allies remain divided on adopting a firm policy for responding to airspace violations. The United States, Poland, and Baltic nations advocate for a forceful stance, while Germany and some southern European countries express concerns about escalation. Earlier, Romania granted its mission commanders authority to shoot down military aircraft entering Romanian airspace, and US intelligence warned of Russian plans to target satellites, potentially disrupting European communications. Hungarian Gripens also intercepted Russian fighter jets near Latvian airspace within the past hour, as confirmed by NATO's main command. Previous reports noted a Russian Borei-class strategic nuclear submarine was spotted near Japan's shores, accompanied by the missile cruiser Varyag and rescue tug Fotiy Krylov. Hungary also offered its combat carrier to Poland following a drone incident, with discussions on a drone wall to protect EU borders upcoming. Ukrainian sources reported strikes on gas distribution stations in occupied Luhansk and drone attacks on Ukrainian positions. Former Russian official Alexander Fedotov was reportedly found dead in the Moscow region, with investigations pointing to suicide, and India requested US approval to import oil from Iran and Venezuela. US President Donald Trump commented, "Putin ought to stop."
