U.S. military prosecutors at Guantanamo Bay have filed war-crimes charges against a former British resident accused of plotting with al-Qaida to bomb apartment buildings in the United States, the Pentagon said this week.

Associated Press reported that Ethiopian national Binyam Mohamed, 30, was charged despite a request from the British government last year to release him from the U.S. Navy base in southeast Cuba.

Binyam is the 20th detainee selected to face the military tribunals at Guantanamo, and the fifth in the last week. A Pentagon official who oversees the tribunal system, Susan Crawford, must approve the charges before an arraignment is scheduled.

Lawyers for Binyam have argued that the U.S. case against him rests on evidence obtained in Morocco, where they allege his genitals were slashed with a scalpel and he was repeatedly beaten during two years of confinement following his capture in 2002.

All the evidence against him appears to have been "derived from coercive interrogation and torture," civilian attorney Clive Stafford Smith and military counsel Air Force Lt. Col. Yvonne Bradley said in a letter urging Crawford to dismiss the charges.

His lawyers filed a lawsuit in London last month seeking to force the British government to hand over documents they claim prove the prisoner was tortured before being sent to Guantanamo in 2004.

Last week he has wrote to Prime Minister Gordon Brown to plead for help in freeing him. He denies involvement with terrorism and writes that any evidence against him has been extracted through torture during six years of detention by the US.

According to the BBC, Binyam was detained in April 2002 as he tried to return to the UK from Pakistan. He says he was taken from there to Afghanistan and Morocco for questioning before being transferred to Guantanamo Bay in Cuba.

The UK government formally requested Binyam's release from Guantanamo Bay in August 2007, along with that of four other British residents. Britain's Foreign Secretary David Miliband formally asked the Bush administration to release British residents at Guantanamo, the BBC said.

Binyam, who was born in Ethiopia and moved to Britain when he was 15, traveled to Afghanistan in May 2001 and trained at an al-Qaida camp, according to the U.S. charge sheet released Tuesday.

The U.S. alleges he later accepted instructions from al-Qaida kingpin Khalid Sheikh Mohammed to conduct terror operations inside the United States. At a meeting in Pakistan, the Ethiopian allegedly agreed to rent apartments inside large buildings in the U.S., fill them with natural gas and blow them up with timing devices.

Binyam faces a maximum sentence of life in prison if convicted on charges of conspiracy and supporting terrorism.

Three of the men were sent to Britain but the U.S. refused to release Mohamed and Saudi-born Shaker Aamer, citing particular security concerns in those cases.

Five British citizens were freed from Guantanamo in March 2004 and four in January 2005, according to Britain's Foreign Office.
