WASHINGTON (Reuters) - President Barack Obama targeted sanctions at close allies and aides of Russian President Vladimir Putin over the Ukraine crisis on Thursday and threatened broad penalties against key sectors of Russia's economy if Moscow moves deeper into Ukraine.
Some of Russia's wealthiest men were cited for sanctions as well as a large Russian bank with ties to Putin's inner circle, in the most significant step Obama has taken to punish Russia for its move to annex the Crimea region of southern Ukraine.
