i'm not sure how reliable this is with all the rumours going around and things that conflict or haven't been proven. but they made the wrong move if they were able to capture the terrorists alive without risking other lives but still killed them.
here are some parts of the article
<Asked specifically if he was talking of torture marks, he said: "It was apparent that most of the dead were tortured. What shocked me were the telltale signs showing clearly how the hostages were executed in cold blood," one doctor said.
The other doctor, who had also conducted the post-mortem of the victims, said: "Of all the bodies, the Israeli victims bore the maximum torture marks. It was clear that they were killed on the 26th itself. It was obvious that they were tied up and tortured before they were killed. It was so bad that I do not want to go over the details even in my head again," he said.
On the other hand, there is enough to suggest that the terrorists also did not meet a clean, death.
The doctors who conducted the post mortem said the bodies of the terrorists were beyond recognition. "Their faces were beyond recognition."
A senior National Security Guard officer, who had earlier explained the operation in detail to rediff.com, said the commandos went all out after they ascertained that there were no more hostages left. When asked if the commandos attempted to capture them alive at that stage, he replied: "Unko bachana kaun chahega (Who will want to save them)?" >
