GULF WAR KUWAIT AFTERMATH

Oil field workers signal to a crane operator as pipe is laid, leading to a burning wellhead in the Ahmadi oil field, Kuwait on Aug. 4, 1991. The pipe will eventually carry crude oil from the well after the fire is extinguished. Over 500 wellheads continue to burn after wellheads were torched by retreating Iraqi troops, who occupied Kuwait for over six months after the Aug. 2, 1990 invasion. (AP Photo/John Gaps III)
