Kyiv left without power after Russian attack

Parts of Kyiv are without power following an attack, as Russia's large-scale invasion of Ukraine, ongoing since February 24, 2022, continues. Russia occupies several regions in eastern and southern Ukraine. US-made Patriot missile interceptors have run out in Ukraine, according to a source cited by CNN on Thursday. The system is crucial for Ukraine's air defense, and President Zelenskyy has warned for months about dwindling stockpiles, but the missiles are only made in the US. Ukraine struck an oil refinery in Ryazan, Russia, its first target after a brief energy ceasefire ended Thursday morning. Russia's defense minister confirmed the attack, and President Putin vowed retaliation. Separately, a tanker was hit by a drone near Romania, with seven crew members missing.
