LONDON (Reuters) -U.S. and European stock markets saw a sudden 0.5% drop in hefty volumes around 1130 GMT on Tuesday, leaving traders scratching their heads and one calling it a "micro flash-crash".

Europe's benchmark STOXX 600 index also turned negative during the quick-fire selloff and was last trading 0.8% lower.
