Oil futures rose to the highest level in more than 30 months as Libyan rebels fought loyalists at an oil port, adding to concern that a protracted conflict in the Middle East and North Africa will curtail supply. Crude for May delivery added 53 cents to settle at $108.47 a barrel on the New York Mercantile Exchange. It was oil's highest settlement since Sept. 22, 2008, when it closed at $109.37 a barrel.
Oil prices have climbed 18 percent since the ouster of Tunisian President Zine El Abidine Ben Ali on Jan. 14, and prices are up 28 percent from a year ago.
