A Pakistani-American cardiologist of the unorthodox Ahmadiyya Muslim sect, who practiced at Baltimore’s Franklin Square Hospital Center in the 1990s, was gunned down last week at a hospital he helped found in southeastern Pakistan.

The slaying of Dr. Abdul Mannan Siddiqui, which Ahmadiyya Muslim Community officials are calling religiously motivated, came a day before the slaying of another AMC official in the nearby hometown city of Pakistan’s new president, Asif Ali Zardari.
