amy: we follow sultana khaya into a small bedroom. pulls back her melhfa -- her traditional sahrawi robe -- and shows me fresh bruises on her leg, both arms and on her breast. amy: sultana, describe what happened to you? >> all of us were participating as sahrawis in the peaceful demonstrations for our right to self-determination. i was trying to gather my sisters for the protest at 5:00. and the whole area was besieged. they were insulting us, beating us, dragging us and using violence to let us know that we weren't going to be able to protest. they tried to single us out and pushed us into narrow streets where they could beat us without anyone observing. what you saw today is nothing compared to what we've witnessed, over and over, since 1975. but the news never gets out. the beatings will not deter us from continuing to fight. even if we die, will be a sacrifice so that our sons and future generations can liven the freedom that we've been denied. amy: other sahrawis have been injured as well. mahfouda lafkir shows us black-and-blue
