Ukrainian and Russian officials said yesterday that Ukrainian drones attacked three refineries, Russian oil tankers in the Sea of Azov, and pipeline pumping stations, in a night of strikes that stretched from the Ukrainian border to the Ural Mountains.

In a separate statement, Ukraine's General Staff and Special Forces said drones targeted the Tanico and Taif-NK refineries in Nizhnekamsk, Tatarstan, the Saratov oil refinery, and the Borisoglebsk air base in the Voronezh region.

Russian officials confirmed strikes in those areas but did not specify which sites were targeted.

Meanwhile, at least 7 people were killed in Russian strikes on Ukraine overnight Tuesday. A large explosion was heard in Kyiv shortly after midnight, before air raid sirens sounded due to a system malfunction that caused panic among residents of the capital.

Several further explosions followed. One person was killed in Kyiv, according to Mayor Vitali Klitschko, who announced that a fire had broken out in a warehouse following a missile strike. In southern Ukraine, a mother and her daughter were killed in the Mykolaiv region in a Russian guided bomb attack, according to Governor Kim Vitali.

Two people were killed in the Kharkiv region and two in the Kherson region, officials said. On the Russian side, Saratov region Governor Roman Busargin announced that one person was killed in a Ukrainian drone attack. The commander of Kyiv's drone force said 21 Russian vessels in the Black Sea and Sea of Azov had been attacked over the past 72 hours.

Russia's Ministry of Defence said it had shot down 415 drones overnight. The full extent of damage caused by the strikes remains unclear. Local media quoted authorities in Tatarstan — located approximately 1,400 kilometres from Ukrainian-controlled territory — as saying a number of people were wounded in the strikes targeting the city of Nizhnekamsk.

The ministry said in a statement that Russian armed forces had shot down and intercepted 903 drones and 8 guided bombs launched by Ukrainian armed forces over the past 24 hours, and that it was making notable advances along all contact lines while inflicting heavy losses on Kyiv regime forces.

On a related note, Russian Ministry of Foreign Affairs spokeswoman Maria Zakharova said Kyiv's refusal to receive the bodies of fallen Ukrainian Armed Forces soldiers is unprecedented in history. Zakharova stated:

There is no entity, no social group in history — and I do not even want to speak of a people — that has not received the bodies of its sons. Even before the emergence of religions, people did not abandon the dead of their homeland.
