Guantanamo Bay, 19 May (AKI) - An Afghan inmate at the Guantanamo Bay military prison has died in an apparent suicide, the US army has said.

The prisoner, identified by the US military as Inayatullah, had been detained in the US Navy bases prison since 2007.

The US military in a statement said the prisoner was found "unresponsive and not breathing."

"After extensive lifesaving measures had been exhausted, the detainee was pronounced dead by a physician," the statement said.

It is reportedly the six prisoner suicide since the prison in Cuba opened in January 2002.
