( CNN ) -- Guantanamo Bay detainees wielding `` improvised weapons '' clashed Saturday with guards , an episode that occurred amid simmering tensions at the U.S. military base . The U.S. guards responded by firing `` four less-than-lethal rounds , '' the military 's Joint Task Force Guantanamo said in a statement . No guards or detainees suffered `` serious injuries '' at the facility in Cuba . The incident , which happened in Camp VI at the detention center , comes as some inmates have waged a weeks-long hunger strike in protest of their treatment , guards searching through Qurans and other issues . Since 2002 , the Guantanamo detention center -- where people have been held in a range of conditions , from communal living to lone , maximum-security cells -- has held people captured outside the United States in counterterrorism operations . As of November 2012 , there were 166 detainees in the facility , according to a government report . Carlos Warner , a U.S. lawyer representing some of those detainees , told CNN late last month detainees have become increasingly frustrated with `` very dire , dire conditions '' and their sense that the current legal process leaves them in limbo indefinitely . `` It leaves them with the prospect of the only way we leave Guantanamo is death , '' Warner said . `` Unfortunately , I think the men are ready to embrace this . '' Early Saturday , the commander of Joint Task Force Guantanamo ordered all inmates in Camp VI moved into individual cells . The reason , the military explained , was `` to ensure the health and security of those detainees . '' The clashes occurred while guards tried to move inmates . Capt . Robert Durand , a Guantanamo spokesman , said the decision was made after detainees starting in February -- about the same time as latest hunger strike -- began obstructing surveillance cameras , windows and glass partitions . These actions , which Durand described as `` non-compliant '' and `` unacceptable , '' made it difficult for guards to do `` round-the-clock monitoring '' throughout the facility . `` Suspending the detainees ' communal living privileges was in response to a coordinated effort by detainees to create an unsafe situation and limit the guard force 's observation , '' the military spokesman said . `` ... The ability to continuously monitor detainees is the only way we can provide for their health and security . We should have gone in earlier . '' Warner , the public defender for some Guantanamo detainees , has said frustrations have grown since a change in command last year , which was followed by a number of new policies . The lack of action in closing Guantanamo Bay -- as President Barack Obama signed on to -- is furthering resentment that those held have no recourse or hope , the lawyer said . `` It was designed ... to be exactly what it is , a legal no man 's land , '' Warner said . `` Where there 's one way in and the only way out is in a box .
