According to AP and AFP, Moscow Mayor Sergei Sobyanin claimed on the 3rd (local time) that about 500 Ukrainian drones that flew into Moscow were shot down by air defense.

The Russian military also dropped 10 3,000 kg bombs on a relief material distribution center in Ukraine's Zaporozhye Oblast, killing at least 33 people. In Kharkiv, medical facilities were destroyed, more than 200 patients were evacuated, and at least 73 were injured.

Both countries also resumed attacks targeting energy facilities. In Ukraine, substations, transformers, and transmission lines were attacked, and the Kstovo oil refinery in Russia's Nizhny Novgorod region also suffered damage from Ukraine's attack.
