Ukraine destroyed six Russian Su-34M jets in missile strike on airfield

Ukraine's navy claimed responsibility for destroying six Russian Su-34M military jets in a missile strike on the Borisoglebsk airfield in Russia's Voronezh region, according to a statement on Telegram. The attack occurred overnight, as other ongoing conflicts targeted energy infrastructure and shipping on both sides, as reported by Reuters.

Earlier in the day, a Ukrainian drone attack on a warehouse in Russia's Ryazan region led to a fire at an oil refinery, the regional governor, Pavel Malkov, announced on Telegram. Emergency services were on-site to assess the damage, which was still being evaluated at the time of the report. The refinery, owned by Russian oil giant Rosneft, supplies fuel to Moscow and constitutes nearly 5% of Russia's oil-refining capacity. It has been a target of multiple drone attacks in recent months.

Malkov also informed the public that classes in schools and kindergartens were canceled in two districts due to a surge in drone attacks. However, neither Ukraine nor Russia had confirmed the recent truce in energy relations announced by US President Donald Trump on Sunday.
