Ukraine launched its largest drone attack yet on Moscow, targeting an oil refinery. The strike occurred while Russian President Vladimir Putin was hosting the ASEAN-Russia summit. The attack resulted in a significant fire at the refinery, though the full extent of the damage remains unclear. Russian officials have vowed to retaliate for the incident, escalating tensions between the two countries. This is the latest in a series of Ukrainian attacks on Russian territory, increasingly reaching the capital. The timing of the attack, coinciding with the international summit, is likely intended to demonstrate Ukraine’s capabilities and resolve.
