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.

A new drone bomber may have joined Ukraine’s escalating assault on Russia’s oil industry. On Wednesday night or early Thursday morning, drones operated by the Ukrainian 14th Separate Unmanned Aerial Vehicle Regiment struck a pumping station on the Druzhba pipeline along the Russian-Belarusian border in Bryansk Oblast.

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.
