GUANTANAMO BAY NAVAL BASE, Cuba — The self-proclaimed mastermind of the Sept. 11 attacks is expected to return to the Guantanamo war crimes court, possibly for the last time.

A military judge has scheduled a hearing Monday at the U.S. base in Cuba to ask Khalid Sheikh Mohammed and two co-defendants if they have objections to another delay in their trial at the request of President Barack Obama's administration.

Mohammed is acting as his own lawyer.
