The US started to use its naval base at Guantanamo Bay, Cuba in 2002 to keep some of Al-Qaeda's suspected members. Since then, it has kept hundreds of suspected prisoners at the facility without any specific evidence against them and/or providing them a fair trial.
A few weeks ago, a group of inmates attempted suicide but were suppressed by brute force. Today again they attempted suicide after a spell of hunger strikes. This time, however, a Yemeni and two Saudis were successful in their attempts.
Quite preposterously, though, the Guantanamo commander called these suicides a 'PR move' and 'an act of war'.
Those inmates were Muslims. Therefore, this can't even be 'an act of war' as Islam doesn't allow suicide. It isn't even an act of war by terrorist standards: It didn't kill American soldiers. It didn't intimidate the (Iraqi and/or Afghan) public by killing a bunch of people in a busy market. Rather, the inmates have been so desperate and hopeless after years of detention that they found no way other than suicide-a religious taboo-to free themselves.
Likewise, considering the United States' history of defiance and disregard to the international law, one can assume that it was clearly not a 'PR move.' All the media attention and criticism over the years against the United States' mistreatment of the prisoners at Guantanamo Bay and other detention centers have yielded very little. Keeping this in mind, it seems preposterous for the inmates to use their lives as a 'PR move' to grab the attention of the international community.
It is, rather, an act of utter frustration and anxiety as a result of years of illegal detention, inhumane treatment, religious and personal humiliation, lack of access to legal counsel, isolation from their families, etc.
