From the Indianapolis Star, with thanks to Ali Dashti:
Islamabad, Pakistan — A former Guantanamo prisoner thought to have forged ties with al-Qaida since his release is leading a militant band whose members have strapped explosives on two Chinese engineers they kidnapped in a lawless region near the Afghanistan border….
The five kidnappers threatened to kill the hostages unless the militants are allowed safe passage to a nearby area where their one-legged leader, Abdullah Mehsud, is believed hiding, officials said.
Mehsud, 28, came back to Pakistan in March after about two years’ detention at the U.S. Navy base at Guantanamo Bay, Cuba. It was not clear why U.S. authorities released Mehsud.
