Attackers killed one Turkish citizen and two Iraqis on a road north of the Iraqi capital, the U.S. military said Monday. The three were killed late Sunday in Tikrit, 130 kilometers (80 miles) north of Baghdad, said Maj. Neal O'Brien, a spokesman for the U.S. Army's 1st Infantry Division. O'Brien said the three were headed to the northern city of Kirkuk. He had no other details and it was not immediately known who the three were working for.
