MIAMI (AP) — Guards clashed with prisoners at the Guantanamo Bay prison Saturday as the military moved hunger strikers from a communal section of the detention center into single cells on the U.S. base in Cuba, officials said.

The commander of the detention center ordered the transfer because prisoners participating in the hunger strike had covered up security cameras and blocked windows, making it difficult to monitor their health during a protest that has lasted more than two months, said Navy Capt. Robert Durand, a military spokesman.
