QUETTA - Central leader of Pakistan Muslim League-N and former minister Sheikh Jaffar Khan Mandokhail said on Saturday that bomb blast in Gwadar was a tragedy. Talking to different delegations here on Saturday, he said that despite spending billions of rupees in the head of security, security situation in the province was worsening rather than improving. He added that unluckily such rulers had been imposed in the province whose claim for progress was limited to Twitter, but on ground, no progress could be seen.  He said that cavalcade of Chinese citizens was attacked in Gwadar, but assailants had not yet been apprehended. He said if the current situation continued, it might cause loss to China Pakistan Economic Corridor (CPEC). He said that government ought to have confessed its incompetency and play role for improving deteriorating law and order situation.
