Rome ? The Italian government said Sunday it was preparing to release its report on the killing of an Italian intelligence agent by U.S. soldiers in Baghdad that would shed light on problems of coordination with American authorities in Iraq and with U.S. rules of engagement at checkpoints.

The Italian Foreign Ministry said it planned to release its version of events in the March 4 “friendly fire” shooting death of agent Nicola Calipari today, two days after the U.S. military reported its investigation had cleared American soldiers wrongdoing in the checkpoint shooting, which also injured Giuliana Sgrena, the Italian journalist that Calipari had just freed from insurgent captivity.

Italy and the United States have differed over crucial points about the incident since the first hours after the killing of Calipari, who was hailed as a national hero at home. The two Italian experts who participated in a joint U.S-Italian probe of the shooting refused to sign off on the American conclusions. After several days of negotiations failed to yield a common final report, both sides agreed to disagree on the findings.

The Italian report will be made public at 11 a.m. today, it said.

The U.S. conclusions have angered Italians and caused friction between the two allies.

The U.S. report released Saturday found the car Calipari was riding in as he headed to Baghdad airport with the ex-hostage had failed to slow down as it approached the checkpoint and the soldiers who fired at it acted in accordance with American military rules of engagement.

The U.S. report contained many blacked-out portions, including the names of the sole soldier who fired at the Italians and other soldiers at the checkpoint as well as their units. But due to an apparent error, the blacked-out portions could be read in some versions downloaded from the Internet.

Rome prosecutors are doing their own probe and have said they wanted to obtain a list of the soldiers at the checkpoint, and the revelation of their names could assist them if the try to prosecute the Americans involved.

The Italian prosecutors handling the separate investigation are awaiting the completion of tests on the car in which Calipari was riding to learn more about the vehicle’s speed and the distance and direction from which the gunfire came. U.S. authorities allowed the bullet-riddled car to be flown to Rome a few days ago.
