The Obama administration on Saturday announced that a Saudi detainee who was an admitted al Qaeda member and helped plan the assassination of Afghan warlord Ahmad Shah Massoud would be sent home from the prison at Guantanamo Bay, Cuba.

The release of Muhammed Murdi Issa Al-Zahrani follows Thursday’s announcement that five other detainees — including four Yemenis, the first since 2010 — had been released to Georgia and Slovakia.
