Barely a week after former Premier Benazir Bhutto’s assassination, a radical Pakistani cleric has issued a “chilling” warning to her son and political heir Bilawal, saying that he “is a target now.”“Bilawal has become the target for those who killed Benazir Bhutto. His party (PPP) has to take extra care of him and look after his security,” Maulana Mohavya Irshad — who admits he is happy to become a suicide bomber — was quoted as saying by a media report here.The 24-year-old bearded cleric, who issued the warning last night at Islamabad’s Lal Masjid where an army operation in July last year had left over 100 people — mostly militants—dead, insisted, “I don’t know which group killed Bhutto on December 27 after she addressed a poll rally in Rawalpindi.”“At this time, I don’t know much about Bilawal. I only know he is a liberal person and that is deviation from Islam. True Muslims will not allow him to go against Islam,” he was quoted as saying by The Sun website.
