Taliban Storm Pakistan School, Kill Mostly Children

For the latest numbers and updates go to CNN.com.

7:51amEST – The Taliban stormed a military-run school in northwest Pakistan on Tuesday, gunning down at least 126 people – most of them children – in one of the volatile Asian nation's deadliest attacks.

Hours after the attack, Pakistani troops were still exchanging gunfire with the militants inside the Army Public School and Degree College in the violence-plagued city of Peshawar, about 120 kilometers (75 miles) from the country's capital, Islamabad.

Two explosions were also heard.

By around 4 p.m. (6 a.m. ET), the Pakistani military had pushed the attackers back to four blocks of the school, military spokesman Gen. Asim BajwaI tweeted. BajwaI over an hour later said that six assailants had been killed.

It was unclear, by then, how many of the hundreds of students at the co-ed school – which is for children of army personnel and has a capacity of 1,000 – were still inside, not to mention how many more were dead or alive. More than 100 people were injured, ministers in Khyber Pakhtunkhwa province said.

"2 more children, 2 teachers rescued," BajwaI wrote around 5:15 a.m. "6th terrorist killed in last block. IEDs planted by terrorists hamper speed of clearance."
