Russian attacks kill four on Saturday; Serbian government faces deadline to oust Russian owners from state oil company. What we know on day 1,362

Ukraine’s army said on Saturday it struck a Russian oil refinery in the Ryazan region near Moscow, as “part of efforts to reduce the enemy’s ability to launch missile and bomb strikes”. Explosions and a large fire were observed at the site, said the military. Ryazan is located about 200km (125 miles) south-east of Moscow.

Russian officials often do not admit such attacks have succeeded, and the Ryazan governor, Pavel Malkov, adopted the standard line that Ukrainian drones were shot down but debris happened to hit the target. “Falling debris caused a fire on the premises of one enterprise,” Malkov said. A wave of 25 Ukrainian drones attacked the region, Malkov said.

Officials in southern Ukraine said four people were killed by Russian attacks on Saturday. Prosecutors in the Kherson region said “three civilians are known to have been killed” in the village of Myklitskyi and the city of Kherson. The governor of the Zaporizhzhia region, Ivan Federov, said a Russian attack killed one person.

The US will not lift sanctions on Serbian oil company NIS unless Belgrade terminates the firm’s majority Russian ownership, Serbia’s energy minister said on Saturday, warning that her country faced “difficult” decisions. Washington sanctioned Petroleum Industry of Serbia (NIS) as part of its crackdown on the Russian energy sector. Analysts say Serbia is on the brink of a winter energy crisis with its lone oil refinery facing a potential shutdown.
