The Office of Foreign Assets Control (OFAC) of the U.S. Department of the Treasury has introduced sectorial sanctions against Russia.

The new sanctions target "a series of large banks and energy and defense firms in what officials described as the most punishing measures to date for Moscow's intervention in Ukraine," nytimes.com wrote.

As BBC reported, on the U.S. Sectoral Sanctions Identification List are Gazprombank, Vnesheconombank, Rosneft oil company, and Feodosiya (oil terminal) enterprise.

Subject to sanctions are also the self-proclaimed Donetsk People's Republic (DPR) and Luhansk People's Republic (LPR).

In addition, the following five individuals were added to OFAC's Specially Designated Nationals List: Deputy Chairman of Russia's State Duma Sergei Neverov, Aide to the President of Russia Igor Shchegolev, Minister for Crimean Affairs Oleg Savelyev, Commander of the Service for Operational Information and International Communications of the FSB, FSB Colonel General Sergey Beseda, and DPR leader Alexander Borodai.
