Rome, Italy, May 5, SPA -- Italian Prime Minister Silvio Berlusconi and U.S. President George W. Bush had a "long and cordial" telephone conversation about the killing of an Italian intelligence agent by American soldiers in Iraq, according to Berlusconi's office. Bush called Berlusconi on Wednesday and "renewed both his personal expression of condolences and those of the government and of the American people for the accident ... in which Dr. Nicola Calipari lost his life," CNN quoted the statement as saying. Calipari, 50, was killed shortly after he secured the release of Italian journalist Giuliana Sgrena, who had been held by insurgents in Iraq. U.S. soldiers opened fire on their vehicle as it approached a checkpoint en route to Baghdad International Airport. Sgrena was shot in the shoulder, but is recovering.--SPA1200 Local Time 0900 GMT www.spa.gov.sa/260106
