wing daily Il Manifesto, Sgrena on Tuesday said the report represented a "step back" as it no longer contemplated the hypothesis that a "tragic mistake" had taken place. The Italian version of events differs in a number of key points from that provided by U.S. soldiers so far. Italy says the car was not travelling at high speed while Sgrena has dismissed suggestions that warning shots had been fired in advance. Sgrena said Tuesday she believed the Italian government may not have adequately informed U.S. officials about the negotiations leading to her release out of concern that its ally would not agree with Italy's handling of the affair. --SP 2259 Local Time 1959 GMT
