AP/Army Times (not an official military outlet) is reporting that
Iraqi officials said Sunday that the gunmen who attacked the provincial headquarters in the Shiite holy city of Karbala, killing five U.S. troops, were wearing military uniforms and drove up in black sport utility vehicles commonly used by foreign dignitaries — an apparent attempt to impersonate Americans.
The account came as confusion mounted over the brazen attack, with the local governor saying the gunmen stormed into the building during a U.S.-Iraqi meeting to discuss security measures ahead of the Shiite Ashoura festival.
In the Karbala incident, provincial Gov. Akeel al-Khazaali, who was not at the security meeting, said the SUVs were able to get through a checkpoint on the outskirts of the city, 50 miles south of Baghdad, because police assumed it was a diplomatic convoy and informed headquarters that it was coming.
–The group used percussion bombs and broke into the building, killed five Americans and kidnapped two others, then fled to the area near Mussayib,” about 20 kilometers to the north, the governor said, adding that Iraqi troops later found one of the SUVs with the three dead bodies dressed in military uniforms.

The Army says all personnel are accounted for and that no one was kidnapped. Perhaps witnesses saw fleeing insurgents in US uniforms and thought that they were captives?
