MIAMI - One of the best known prisoners in Guantanamo says a hunger strike at the U.S. base in Cuba has grown to include 130 men in a protest over their confinement.

Shaker Aamer tells his lawyer that he has lost 32 pounds during the strike that began Feb. 6. Aamer says prison officials have been trying to break the strike without success.

Aamer was born in Saudi Arabia but has been a resident of both Britain and the U.S. There has been an international campaign to free him after he's spent more than a decade at the prison without charges. U.S. officials have accused him of links to terrorism.

Aamer spoke to his lawyer Friday about the strike. A prison spokesman said Monday that 39 prisoners are on strike, up two from last week.
