A rocket hit a site in southern Iraq used by foreign oil companies on Wednesday, including U.S. energy giant ExxonMobil, wounding three people and threatening to further escalate U.S.-Iran tensions in the region.
There was no immediate claim of responsibility for the attack near Iraq's southern city of Basra, the fourth time in a week that rockets have struck near U.S. installations. A second rocket that landed in another nearby area did not explode, one official said.
Three previous attacks on or near military bases housing U.S. forces near Baghdad and Mosul caused no casualties or major damage. None of those incidents was claimed.
