As children gathered outside a private school in Karachi Pakistan to receive test scores and prizes, a man threw two grenades and opened fire at the school. The school's principal was killed, and six children were wounded.
A man armed with a gun and grenades attacked a school in southern Pakistan during a prize distribution ceremony on Saturday, killing its principal and wounding six children before fleeing.
Police officer Nasir Mehmood said the attacker struck as dozens of children were gathered outside at their private school in Karachi to receive the results of their annual exam.
TV showed panicked relatives of the wounded children, who were between the ages of 8 and 10, crying outside the school in the port city's Ittehad Town neighborhood.
There was no immediate claim of responsibility.
Another police officer, Asif Ijaz Sheikh, said the slain principal was a local leader of the Awami National Party (ANP). He said police were still investigating the identity of the attacker, who threw two grenades and then opened fire on Khan and children who were standing near him.
Karachi has been the scene of scores of bomb and gun attacks in recent years. Gangs controlled by various groups, including the city's two main political parties the Muttahida Quami Movement and the ANP, have also been blamed for targeted killings of their rivals.
