KARACHI. The Karachi university van blast, which claimed the lives of three Chinese nationals, has apparently exposed the security lapses in the varsity and the prevailing flow of communication between the security and the administration.

The investigation led by police and other security agencies into the Karachi university van blast is under way. Sources said that Rangers had written four letters to the varsity administration and highlighted the imminent risk to the lives of Chinese nationals. But, they “did not” pay any attention to the concerns.

Sources added that the KU administration had written letters to the Chinese institute. A wing of Rangers working in the university tried to contact the administration and the registrar for a meeting on such concerns on several occasions. But, “no one tried to come in front for the security” and it resulted in the van blast incident.
