Authorities have beheaded a Saudi man convicted of murder and a Pakistani for drug trafficking, the Interior Ministry said. The Pakistani was arrested while trying to smuggle heroin into the kingdom, the ministry said in a statement carried Thursday by Saudi Press Agency. It identified him as Qal Moazzam Khan. He was convicted and executed in the capital Riyadh. Saudi Abdulla Bin Mohammed al-Subaie was also beheaded for stabbing to death another Saudi in a dispute. Saudi Arabia follows a strict interpretation of Islam under which those convicted of murder, drug trafficking, rape or armed robbery are executed in public with a sword. Thursday's executions brought to 39 the number of people beheaded this year, according to an Associated Press count.
