One of the oil wells set ablaze by retreating Iraqi troops in the southern Iraq Rumaila oil field (and one in the distance). The wells were set on fire with explosives placed by retreating Iraqi troops when the US and UK invasion began in March of 2003. Seven or 8 wells were set ablaze but at least one other was detonated but did not ignite. The Rumaila field is one of Iraq's biggest with five billion barrels in reserve. Rumaila is also spelled Rumeilah.
