#AP | Sheik Ali Salman, head of the Shiite opposition Al Wefaq society, speaks to The Associated Press at his office in Manama, Bahrain, on Sunday, Nov. 11, 2012. Envoys from the U.S. and other countries are acting as intermediaries with the Gulf nation's rulers in attempts to ease 21 months of unrest, the head of Bahrain's main opposition group said Sunday. Even so, he said protest groups see little hope for breakthrough dialogue as crackdowns widen. The remarks by Salman, head of the top Shiite political bloc Al Wefaq, underscore the sense of a deepening crisis in strategic Bahrain after a week that included deadly bomb blasts and an expanded deployment by the paramilitary National Guard.
