The additional sanctions, over Russian involvement in the Ukrainian conflict, will involve Russia's oil sector, defense equipment and intelligence technologies, the sources said. Access to capital by Russian state banks, and travel bans and freezes of assets of certain individuals, will likely be restricted as well.
Details of the agreement are emerging, and a full sanctions statement from EU headquarters in Brussels, Belgium, is expected Wednesday. The aim of the EU is to increase the economic burden on Russia due to its support of the separatist movement in Ukraine, and because of evidence from Western governments that the separatists were responsible for shooting down Malaysia Airlines Flight 17 as it passed over rebel-held Ukrainian territory on July 17.
U.S. Secretary of State John Kerry said the United States is preparing additional sanctions.
