An Italian journalist freed after a month as a hostage in Iraq has been taken to a Rome hospital, one day after U.S. troops fired on a car she was in, wounding her and killing an Italian intelligence officer who was with her.

Journalist Giuliana Sgrena, a correspondent for the Italian newspaper Il Manifesto, was greeted Saturday by Italian Prime Minister Silvio Berlusconi on her arrival in the capital.

Ms. Sgrena was wounded Friday when U.S. forces mistakenly fired on her car at a checkpoint near Baghdad airport.  An Italian secret service agent (Nicola Capilari) who tried to protect her was killed in the shooting. 

President Bush telephoned Italy's prime minister to express regret for the shooting and promised a full investigation.

Ms. Sgrena told reporters she was not mistreated during her month in captivity. She was taken to an Italian military hospital from the airport.

Ms. Sgrena was kidnapped February fourth by gunmen who demanded Italy withdraw its three thousand troops from Iraq.
