Report: Muslim Brotherhood Gaining Foothold in Boston

Tamerlan had traveled to al Qaeda hotbeds in southern Russia, where authorities believe he may have met with known jihadists.
But closer to home, he and his brother attended a Boston-area mosque with ties to the Muslim Brotherhood.

Locals fear that the Brotherhood is putting young Boston-area Muslims on the path to radicalization.
