The United States will try September 11 attacks mastermind Khalid Sheikh Mohammed, as well as four other 9/11 terror plotters, in New York City. Federal sources say that U.S. Attorney General Eric Holder will make the announcement today; President Obama didn't confirm the details, but did say from Japan, "I am absolutely convinced that Khalid Sheikh Mohammed will be subjected to the most exacting demands of justice."

Mohammed was captured in 2002, after being in various prisons (the NY Times reminds, "Documents have shown that the CIA used waterboarding — a controlled drowning technique — against Mr. Mohammed 183 times in March 2003"), and moved to Guantanamo Bay in 2006. In February 2008, the Pentagon finally charged Mohammed and other suspects and he pleaded guilty to the charges in December, but these were military commissions from the Bush era "before the Obama administration froze those proceedings." The Times adds, "It was not clear what charges they would now face in civilian court."

ABC News reported yesterday, "Officials in New York say they have not been informed of any decisions, but Manhattan's federal courthouse has often been cited as a "sentimental favorite" for the 9/11 trials. Like the now-destroyed World Trade Center, it is in lower Manhattan. The Southern District is also one of the jurisdictions in the United States with the most experience trying terrorism cases."
