Copper touches three-week low

Base metals fell broadly on Tuesday, with copper at a three-week low, as worries about tensions in North Africa and the Middle East knocked risk appetite, while a higher dollar deterred non-US investors. Libya's Muammar Gaddafi used tanks and warplanes to fight a growing revolt, witnesses said, and scoffed at reports he was fleeing after four decades in power. The revolt is the latest in a wave of protests across North Africa and the Middle East that this year have already deposed the leaders of Tunisia and Egypt. Three-month copper on the London Metal Exchange was at $9,660 a tonne at 1014 GMT versus $9,810 a tonne at the close on Monday. It hit a session low of $9,635 a tonne, its lowest since the end of January, losing grip of a record high of $10,190 hit on February 15. Stocks of copper in LME warehouses last rose 275 tonnes to 411,750 tonnes, their highest since August 2010.
