The EU has adopted new economic sanctions against Russia over the conflict in Ukraine, targeting the oil sector, defense equipment and sensitive technologies, EU sources said. Russian state banks' access to capital is also likely to be restricted, the BBC news reported. The aim is to increase the cost to Russia of its continued support for pro-Moscow rebels in eastern Ukraine. Full details of the new EU sanctions are expected on Wednesday, when the EU is also set to name more Russian officials facing asset freezes and travel bans in Europe.
