The Pentagon released a transcript where Khalid Shaikh Mohammed has confesses to planning the September 11 attacks, as well as other terror attacks, during a tribunal hearing. The NY Times notes that the hearing "also summarized some of the evidence the Pentagon says supports the designation of Mr. Mohammed as an enemy combatant." Mohammed has been in U.S. custody since his capture in 2003.
The Times also offered an excerpt of his "rambling" confession where he says he's sorry about killing so many people.
Because war, for sure, there will be victims. When I said I’m not happy that 3,000 been killed in America. I feel sorry even. I don’t like to kill children and the kids. Never Islam are, give me green light to kill peoples. Killing, as in the Christianity, Jews, and Islam, are prohibited. But there are exception of rule when you are killing people in Iraq. You said we have to do it. We don’t like Saddam. But this the way to deal with Saddam. Same thing you are saying. Same language you use, I use. When you are invading two-thirds of Mexican, you call your war manifest destiny. It up to you to call it what you want. But other side are calling you oppressors. If now George Washington. If now we were living in the Revolutionary War and George Washington he being arrested through Britain. For sure he, they would consider him enemy combatant. But American they consider him as hero.
Well, he's certainly read up on American history.
And here's the list of attacks, both carried out and planned, that Mohammed claims responsibility for - 6. Planning attacks against several prominent American skyscrapers...10. Planning to bomb several New York landmarks, including the stock exchange and suspension bridges.
