BASRA, Iraq (Reuters) - 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.
