Another steep decline in Variable Risk Landscape came with oil prices climbing to a 13-year high after two deadly attacks on oil installations within a week. The killing of five Western contractors at Saudi Arabia's western oil hub in Yanbu and the attempted suicide bombing of Iraq's main oil export terminals on April 24 have raised market-rattling fears that oil workers and facilities may be Al Qaeda's new targets of choice. The price of crude oil jumped above $40 a barrel in New York on Friday, its highest level since Iraq invaded Kuwait in 1990. The images of US soldiers torturing and humiliating Iraqi detainees in notorious Abu Ghraib prison in Baghdad provoked the fear of a new wave of terrorist attacks.
