VAUGHAN, Ontario (AP) — A North American cardiologist shot dead in Pakistan in front of his wife and two-year-old son was remembered Wednesday as a selfless humanitarian who was murdered because of his faith.

A burial ceremony for Dr. Mehdi Ali Qamar saw impassioned calls for Canada to pressure Pakistan to better protect religious minorities against extremism. Qamar, 51, was originally from Pakistan and belonged to the minority Ahmadiyya Muslim sect, also known as Ahmadis. He was a dual American and Canadian citizen who had lived in Ohio for the last decade.
