A former London-based film director has been brutally murdered and dismembered by his parents in an honour killing after he returned to his home country of Iran, police said. The chopped up body of Babak Khorramdin, 47, was found in rubbish bags and a suitcase in the town of Ekbatan, western Tehran, on Sunday. An argument had broken out between the father and son over Babak’s unmarried status, according to reports.
