Oil prices rose this morning as the civil war in Libya continues and investors anticipate a fall in US stockpiles.

US crude gained 62¢ to stand at $85.04 a barrel and Brent crude rose by 33¢ to $108.69 a barrel due to Libyan unrest, which has halted the country’s oil production.

The civil war, which was expected to come to an end on Monday, was extended after armed forces loyal to Libyan leader Muammar Gaddafi fought rebels in Tripoli.

US crude inventories were forecast to have fallen due to lower imports, according to a preliminary Reuters poll on Monday ahead of weekly data due on Wednesday.
