on Tuesday in volatile trade as a possible referendum in Greece
on its debt bailout revived concerns about the euro zone and
weak global economic data pointed to further slowing.
Brent and U.S. crude fell a third straight session, but
both pared losses after a media report said there was growing

Papandreou's call for a referendum.
Papandreou's unexpected move had sent the euro, equities

Brent's premium to its U.S. counterpart CL-LCO1=R

Brent 3 percent below its 30-day average. Both surpassed half a
million lots traded and topped the previous session's totals.
