KIEV (Reuters) - Republican U.S. Senator John McCain promised on Saturday continued support for Kiev in the face of aggression from Moscow, as he spent New Year's Eve on the front line in Ukraine's eastern conflict zone.

McCain was one of a bipartisan group of 27 U.S. senators who sent a letter to President-elect Donald Trump in December, urging him to take a tough line against Russia over what they termed its "military land grab" in Ukraine.
