100 Guantanamo prisoners on hunger strike

At least 100 of 166 prisoners at the US base in Cuba's Guantanamo Bay have now joined a hunger strike.

At least 100 of 166 prisoners at the US-run Guantanamo military prison have joined a hunger strike.

A hunger strike among prisoners at Guantanamo Bay keeps growing.

Spokesman Lieutenant Colonel Samuel House said on Saturday 100 of 166 prisoners at the US base in Cuba have now joined the strike.

He says 19 are receiving liquid nutrients through a nasal tube to prevent dangerous weight loss. Five of those are at a hospital under observation but do not have any life-threatening conditions.

Lawyers for the detainees say the military is undercounting the number of hunger strikers.

Prisoners began the hunger strike in February to protest conditions and indefinite confinement.
