WASHINGTON — Pentagon prosecutors have made a renewed effort to charge three prisoners at the Guantánamo Bay wartime prison with conspiring in two deadly terrorist bombings in Indonesia in 2002 and 2003.

The prosecutors have tried unsuccessfully twice before to move the case ahead, but the office overseeing military commissions never signed off on the charges. If the charges are approved this time, it would be the first new case to head toward trial at Guantánamo Bay, Cuba, since 2014.

The prosecutors are seeking to charge the prisoners — an Indonesian captive known as Hambali and two Malaysian men — with murder, terrorism and conspiracy in the 2002 nightclub bombings in Bali, which killed 202 people, including seven Americans, and the 2003 Marriott hotel bombing in Jakarta, which killed at least 11 people and wounded at least 80, including three Americans.

The three men have been held at Guantánamo since September 2006. They were captured in Thailand in August 2003 in a joint Thai-United States intelligence raid and spent about three years in the secret C.I.A. prison network.
