The measures constituted the broadest U.S. package of sanctions so far targeting Russia's oil and gas revenues.

The U.S. Departments of Treasury and State Friday applied new sanctions on Russia's oil production and exports. Sanctioned were oil companies, 183 ships, dozens of oil traders, insurance companies and energy officials.

The White House, now unconcerned about the effect on gas prices and inflation, blacklisted two of Russia’s biggest oil producers and nearly 200 tanker ships.
