LONDON European shares fell in thin trade on Monday while the dollar powered ahead after U.S. Federal Reserve Chair Janet Yellen indicated that the central bank was poised to raise interest rates this year.

The pull-back in European stocks mirrored losses on Wall Street on Friday after Yellen suggested the Fed was ready to act if the economy kept improving as expected, though a raft of recent data has suggested it is growing only modestly in the second quarter.
