He had gone back to resume fighting the jihad. And what was preventing him? Guantanamo does nothing to disabuse inmates of the jihad ideology. From AP, with thanks to Douglas:
KANDAHAR, Afghanistan “” A former inmate at the U.S. prison camp at Guantanamo Bay, Cuba, who returned to Afghanistan to rejoin the Taliban as a key commander, was killed along with two fellow fighters in a raid by Afghan security forces, two senior officials said Sunday….
The Taliban commander, Maulvi Abdul Ghaffar, died along with two comrades in a gunbattle Saturday night in Uruzgan, a southern province, said Gov. Jan Mohammed Khan.
He said authorities had received intelligence that Ghaffar was hiding in a village called Pishi and was planning an attack against the government. Security forces launched the raid after surrounding the house where the militants were hiding. No Afghan forces were reported hurt.
The governor said Ghaffar had been a senior Taliban commander in northern Afghanistan and was arrested about two months after a U.S.-led coalition drove the militia from power in late 2001. He was held for eight months at Guantanamo Bay before his release and return to Afghanistan.
Khan and Afghan Interior Minister Ali Ahmad Jalali Khan said Ghaffar was then appointed leader of Taliban fighters in Uruzgan, a rugged region believed to be a stronghold of the hardline Islamic militia.
U.S. military officials said they could not immediately confirm Ghaffar had once been in U.S. custody.
Taliban-led insurgents are active in much of southern and eastern Afghanistan and frequently launch attacks on the U.S.-backed government despite the deployment of thousands of U.S. forces to hunt them down.
