Uruguay's president is asking the United States to free three Cuban prisoners in exchange for receiving five Guantanamo Bay detainees.

The Cuban prisoners were sentenced in 2001 on charges including conspiracy and failing to register as foreign agents. Jose Mujica said Friday that the U.S. should release them.

Mujica indicated Thursday that he's open to taking in some former terror suspects still held at Guantanamo.

He said Friday that he wants to help bring an end to the Guantanamo base calling it a "an embarrassment on humankind."

U.S. officials have repeatedly rejected appeals to release the three Cuban spies still held or to exchange them for an American held in Cuba.

President Obama has pledged to close the prison on the U.S. base in Cuba but was thwarted by Congress.
