The US expanded sanctions against Russia over the Ukraine crisis on Friday, adding more individuals onto the blacklist, including a deputy energy minister and energy companies, the Treasury Department said.

Russian Deputy Energy Minister Andrey Cherezov and energy company Technopromexport are among those who were hit with sanctions, according to the list published on the website of the US Treasury Department on Friday.

The newly imposed sanctions target Gaz-Alyans and Kaliningradnefteprodukt energy companies, as well as the Power Machines group.
