Osama bin Laden has been making another audio recording, and this time he's promising to get revenge if Khalid Sheikh Mohammed is executed. Bin Laden says, "The White House has declared its wish to execute (Mr Mohammed and the other suspects). The day the United States takes such a decision, it would be also taking the decision that any of you falling into our hands will be executed."

Mohammed and others involved in the September 11 attacks are currently awaiting trial, either civilian or military. Bin Laden also says on the recording, "It is fair to treat each other the same. War is a back-and-forth. The White House politicians were and still are oppressing us, particularly in providing support to the Israelis and occupying our land in Palestine. They were thinking that America was safe behind oceans from the anger of the oppressed until the reaction was strong in your house on the 11th." (Another translation of the recording offers, "They used to think that America across the oceans is protected from the rage of the oppressed until our reaction was loudly heard at your home on the 9/11 with God's help.") We previously heard from bin Laden when he blamed the U.S. for global warming in January.

As it happens, a collection of oral histories from September 11 is being unveiled today. They will be available for the public to listen to at the 9/11 Memorial Preview site.
