The Defense Department transferred three Guantanamo Bay detainees to their home countries this week, leaving the number of detainees at the infamous prison below 30.

Mohammed Farik bin Amin and Mohammed Nazir bin Lep, both of whom were convicted in connection with the 2002 Bali bombings, a series of terrorist attacks on that day that left more than 200 people dead, have been repatriated back to the Malaysian government after pleading guilty to all the charges against them and agreed to testify against the alleged ringleader of that and other attacks. They worked closely for years with Encep Nurjaman, known as Hambali, an Indonesian leader of the al-Qaida affiliate Jemaah Islamiya, who is also detained at Guantanamo Bay.
