U.S. crude oil prices deepened early losses to fall below $70 a barrel for the first time in two weeks after Iraqi television reported the death of al Qaeda's leader in Iraq, Abu Musab al-Zarqawi. U.S. crude traded down 85 cents to $69.97 a barrel by 0735 GMT, falling about 35 cents following Iraqi television and U.S. ABC News reports of Zarqawi's death, apparently in an air raid near Baghdad.
Oil exports from Iraq have failed to return to pre-war levels due to frequent sabotage attacks on the country's northern pipeline and deteriorating security that has prevented significant investment in aging southern oilfields.
