Tragedy  in the northwestern Parkistani city of Peshawar as taliban gunmen stormed a military-run school today, killing at least 84 people. According to state officials this is the worst attack to hit the country in over a year.

Majority of the victims were students at the army public school, which has children and teenagers in grades 1-10.

The siege was carried out by militants from the Tehreek-e-Taliban group, a Pakistani militant group trying to overthrow the government.

The attack began in the morning hours, with about half a dozen gunmen entering the school — and shooting at random, said police officer Javed Khan. Army commandos quickly arrived at the scene and exchanged fire with the gunmen, he said.

Pervez Khattak, the chief minister of the province where Peshawar is located, said 84 died but that death toll could rise further in the unfolding drama.

Khattack said fighting was still underway and that roughly the same number of students have been wounded. He said the 84 killed were all "children" but hospital officials earlier said at least one of the fatalities was a teacher and that one security official was also among the dead.

The school is located on the edge of a military cantonment in Peshawar, but the bulk of the students are civilian.

Taliban spokesman Mohammed Khurasani claimed responsibility for the attack in a phone call to media, saying that six suicide bombers had carried out the attack in revenge for the killings of Taliban members at the hands of Pakistani authorities.

According to reports, dozens of wounded persons are flooding into local hospitals as terrified parents search for their children in the midst of the chaos.
