Judge Pohl wanted to continue the trial of Abd al-Rahim al-Nashiri over the attack on the ship off Yemen, which left 17 US service personnel dead and 50 injured. Pentagon officials said Judge Crawford had dismissed the charges against Nashiri without prejudice, meaning new charges could be brought against him. Mr Obama, who intends to close the detention centre within a year, was expected to meet relatives of those killed in the USS Cole attack today.
