The 15 British sailors and marines freed last week said they were mistreated by their Iranian captors. They said they were blindfolded, interrogated and held in isolation. The 15 were released on Wednesday, one day after a kidnapped Iranian diplomat was freed in Iraq. The diplomat, Jalal Sharafi, said he was tortured and questioned by U.S. intelligence officers during his time in captivity. He said U.S. intelligence officers interrogated him about Iran’s presence in Iraq. The U.S. continues to hold five Iranian officials in Iraq. Over the weekend, Iran warned that it would stop cooperating with the government of Iraq if the officials are not released.
