WASHINGTON — The United States has transferred two Malaysian detainees at the Guantanamo Bay U.S. military prison to their home country after they pleaded guilty to charges related to deadly 2002 bombings in Bali and agreed to testify against the alleged ringleader of that and other attacks, the Pentagon said Wednesday. Prosecutors say Mohammed Farik bin Amin and Mohammed Nazir bin Lep worked for years with Encep Nurjaman, known as Hambali, an Indonesian leader of al-Qaida affiliate Jemaah Islamiyah. That includes helping Nurjaman escape after bombings on Oct. 12, 2002, killed 202 people at two nightspots in Bali, U.S. officials
