At least 19 people have been killed and 45 injured in Southern Karachi gambling den blast. The Rummi club, situated on infamous Nappier road, Karachi had it's own security system and CCTV cameras. Astoundingly such activities were taking place under the nose of government without any let or hindrance. Is it not state within the state? Law enforcement agencies should first be brought to book for not checking the gambling den, one of the largest of country. How shameful is it that the event has been reported by International media putting a question mark on the vigilance of the law enforcement agencies. IFTIKHAR SHAHEEN MIRZA, Islamabad, April 22.
