"BOSTON — The mosque attended by the two brothers accused in the Boston Marathon double bombing has been associated with other terrorism suspects, has invited radical speakers to a sister mosque in Boston and is affiliated with a Muslim group that critics say nurses grievances that can lead to extremism.
Several people who attended the Islamic Society of Boston mosque in Cambridge, Mass., have been investigated for Islamic terrorism, including a conviction of the mosque's first president, Abdulrahman Alamoudi, in connection with an assassination plot against a Saudi prince.
Its sister mosque in Boston, known as the Islamic Society of Boston Cultural Center, has invited guests who have defended terrorism suspects. A former trustee appears in a series of videos in which he advocates treating gays as criminals, says husbands should sometimes beat their wives and calls on Allah (God) to kill Zionists and Jews, according to Americans for Peace and Tolerance, an interfaith group that has investigated the mosques."
