An inmate wounded in a bloody Afghan prison shootout will be questioned to determine if he and four comrades, all once suspected of belonging to Al Qaeda, were trying to escape or may have been planning to attack three American prisoners, the jail warden said Saturday.

Officials initially said four inmates — three Pakistanis and an Iraqi — were involved in the daylong fray at Kabul's notorious Pul-e Charkhi (search) jail that left them and four guards dead. But warden Abdul Salam Bakhshi (search) said Saturday that another prisoner who was wounded also was involved from the start.

"We are going to question him, and he will tell us why they attacked, what was their target, whether they wanted to escape or what was their aim," Bakhshi said.

He said it was possible that the men were trying to get to the three Americans, who are being held in a different part of the prison while serving sentences of eight to 10 years for allegedly torturing Afghans while on a freelance hunt for terrorists.

Jonathan Idema, Brent Bennett and Edward Caraballo are seeking to overturn their convictions in a trial that embarrassed U.S. and NATO forces and sowed confusion about Washington's role in Afghanistan.

Idema's attorney, John Tiffany, said his client called him from the prison and said the Americans had been targeted for death by the inmates who attempted the jailbreak.

Idema made other claims during his sometimes-bizarre trial, saying he was in daily contact with U.S. officials "at the highest level," including Defense Secretary Donald H. Rumsfeld's office — but the U.S. government has described him as a vigilante working on his own. He had also accused the FBI of orchestrating his arrest.

A patrol of four German armored personnel carriers from the International Security Assistance Force (search) was dispatched to the scene, along with several U.S. liaison officers, but they deliberately took a hands-off approach, letting Afghan troops and police handle the incident.

"While ISAF is prepared to assist the government in the provision and maintenance of a stable environment without our area of operations, we will not normally intervene in this type of situation, unless specifically requested by the government," ISAF spokesman Lt. Cdr. Ken Mackillop told reporters.

Afghan troops stormed the crumbling, overcrowded Pul-e Charkhi jail — which holds Taliban and Al Qaeda suspects as well as common criminals — just after nightfall Friday with small arms and rocket-propelled grenades, ending the 10-hour standoff.

The five inmates used razors to attack a guard leading them to morning prayers. They took his AK-47 rifle, then beat and stabbed him to death, Bakhshi said.

A gunbattle ensued that killed three other guards and two of the would-be escapees. A third inmate was wounded, and the other two, both Pakistani, scavenged a second gun and barricaded themselves with both rifles on the jail's war-damaged second floor, Bakhshi said.

They then took potshots at hundreds of security personnel ringing the jail, keeping them from reaching three wounded soldiers inside the complex.

Jail officials used a loudspeaker to warn prisoners to "surrender or die." The inmates responded with gunfire.

The five inmates had all once been held in a northern jail run by Gen. Abdul Rashid Dostum, one of country's most powerful warlords, on suspicion of fighting alongside Al Qaeda and the Taliban, though they were all released earlier this year, suggesting they were not considered high-level militants. They were re-arrested in Kabul for unspecified common crimes several months ago.

Pul-e Charkhi, located on the capital's outskirts, was the scene of summary executions under a series of Afghan regimes, most recently the hard-line Taliban. In August, a U.N. human rights expert urged the immediate release of an estimated 725 Taliban fighters taken prisoner in 2001, saying they were living in conditions that violate "every standard of human rights."

The jail is unrelated to the detention facilities that the U.S. military runs for captured Taliban and Al Qaeda fighters.
