Military judges have dismissed charges against a Guantanamo detainee who chauffeured Osama bin Laden and another who allegedly killed a US soldier in Afghanistan.

Former Guantanamo detainees have organised a jailbreak in Afghanistan, kidnapped Chinese engineers and taken leadership positions with the Taliban, the US military says.

The US military has filed murder charges against Omar Khadr, a Canadian who was a teenager when he was captured in Afghanistan and sent to the Guantanamo Bay prison in 2002.

The remains of three men who committed suicide at the US prison at Guantanamo Bay have been sent home, the Pentagon said.

The United States has stopped press access to Guantanamo Bay as the prison comes under renewed criticism for the apparent suicides of three detainees last weekend.

The American military flew in two forensic specialists today to examine the body of slain al-Qaida chieftain Abu Musab al-Zarqawi “to see how he actually died” in an effort to reconstruct the last minutes of his life, a US general said.
