Ukraine launches second major drone attack against Russian oil refineries in a week - Intelligence sources say one refinery had been hit by four Ukrainian drones, causing ‘significant damage”

A Ukrainian drone attack last week forced a refinery in Ryazan, southeast of Moscow, to suspend operations. Russia's Defense Ministry said in a statement on Friday that 49 Ukrainian drones had been downed over the country overnight, including 25 in the southern Rostov region and eight in the Volgograd region.

Officials say a Russian drone has blasted a hole in an apartment building in northeastern Ukraine during a nighttime attack that killed at least six people and wounded nine others.
