A human rights lawyer says a growing number of inmates at Guantanamo Bay have joined a hunger strike.
David Remes says out of 166 prisoners, around 130 are now on strike, in protest against conditions and indefinite confinement.
He says the U.S. military has acknowledged that 100 inmates are on strike.
Remes, who represents 17 detainees at the camp, says some inmates are being forced-fed.
The U.S. military is sending additional medical help to the camp as the strike continues.
It began early February, when guards seized belongings during a search.
