WASHINGTON (Reuters) - A U.S. sanctions team is in Europe this week discussing possible deeper sectoral penalties against Russia if a ceasefire deal with Ukraine is further violated, a senior State Department official said on Wednesday.

Victoria Nuland, U.S. assistant secretary of state for European affairs, told a congressional hearing there were new concerns about heavy shelling and fighting around Donetsk and on the road to Mariupol by pro-Russian separatists.
