By Thomas Grove MOSCOW (Reuters) - Russian authorities accused Ukraine of trying to kill law enforcement officials who were checking reports of cross-border shooting on Friday by firing a volley of mortar rounds over the frontier into Russia. A Russian security official said up to 40 mortar bombs fired by Ukrainian forces had fallen in the Russian province of Rostov near the border where Ukrainian government forces are fighting pro-Russian separatists. "Those who shot from Ukraine carried out the shooting purposefully with an intent to kill Russian law enforcement officials," said Russia's Investigative Committee, which answers only to President Vladimir Putin.
By Lesley Wroughton and Warren Strobel WASHINGTON (Reuters) - Evidence that Russia is moving more weapons into Ukraine to arm rebels is likely to trigger more U.S. sanctions against Moscow once the European Union likely agrees its own sanctions next week, senior U.S. officials said on Friday. “If the EU pulls together a package of sanctions in the coming week, the U.S. would want to complement that,” said a European diplomat in Washington, who requested anonymity to discuss diplomatic strategy. The new willingness in Europe to impose sanctions on prominent Russians and sections of the economy, partly because of horror at the downing of a Malaysian airliner over Ukraine last week, has been welcomed by the United States.
