Yemen has freed 170 men suspected of having ties to al-Qaeda, reports AP. The men were released to tribal chiefs after signing pledges to renounce terrorism. Yemeni military spokesmen say troops are poised to sweep through the al-Qaeda stronghold of Marib. Though such releases have often raised US hackles, Yemeni officials expect most of the 100 remaining Yemenis at Guantanamo will be sent home now that President Obama has ordered the prison shut.
