According to reports, when cadets were busy in the morning drills, a teenager boy in a school uniform, walked in to the campus and triggered a blast by blowing himself up. Among the casualty are 20 wounded cadets and security officials.
The attack has once again challenged Pakistani official observations on the weakening of al Qaeda and Taliban in Pakistan.
In a statement condemning the attack, Prime Minister Yusuf Raza Gilani said, "Such cowardly attacks cannot affect the morale of the security agencies and the resolve of the nation to eradicate terrorism."
The Pakistani government is under pressure on several fronts as it tries to revive a economy in doldrums as well as mitigate the growing influence of radical elements in the country.
In addition to all these it is also trying to ensure that political stability remains at the centre as well as in the volatile north western region of the country.
