A roadside bomb exploded Tuesday near a passing convoy of Iraqi security guards and foreign contract workers south of Basra, killing four people, police said.
Capt. Mushtaq Kadim of the Basra Rapid Response Unit said the four dead were Americans. But U.S. diplomatic and military officials in Baghdad were unable to confirm the report, saying only that the victims were not diplomats or soldiers.
Associated Press Television News videotape showed a wrecked SUV at the side of the highway near Zubair, about 30 kilometers (20 miles) south of Basra. British soldiers and Iraqi police blocked off the area.
