Two towns in Russia's western Kursk region lost electricity and a man was wounded on Wednesday after Ukraine dropped explosives on an electricity substation near the border overnight, the region's governor said.

"One of the workers received shrapnel wounds while restoring power supply. He is in the central district hospital and doctors are giving him all necessary treatment," governor Roman Starovoyt said.

Reuters was not able to independently verify his account. (Reporting by Reuters; editing by Guy Faulconbridge)
