According to abdul ghaffoor PML-N this is "azabi elahi" because of data Darbar bomb blast ,ahmadia mosque blast and others but no one is arrested and who are arrested ,no action against them is taken at all.There are reports like police,there are some black sheeps in ISI not all who are behind these killers along with the politicians thats why no action taken.can we be sincere with our nation.who is behind them,low level or high level people ,action should be taken.we are destroying our own country ourselves but how long.Lets get serious and get tough with these killers.some of religious fanatics are also involved,i would like to add kamran Shafi's statement in Dawn which he asked very valuable questions to intelligence agencies who are considered # 1 then why the blasts took place in their presence.its upto to the agencies to answer these questions,why not a single terrorist is hanged ,"azabi elahi" have to take place when cruelty and injustices taking place in the country.
