The Israeli military has admitted that its initial accounts of the killing of 15 people in Gaza last month were partly mistaken. The admission came after a video obtained by The New York Times contradicted the military's earlier version of events. The military official briefing reporters did not offer an explanation for the contradiction, other than to say that the initial account had been 'mistaken.' The Israeli military had previously claimed that the vehicles were 'advancing suspiciously' towards the troops, but the video shows that the ambulances and fire truck were clearly marked and had their emergency signal lights on when they were hit with gunfire.
