UPDATE: Death Toll Rises To 137 In Pakistan School Terrorist Attack

Islamabad, Pakistan (CNN) - "'God is great,'" the Taliban militants exclaimed, as they roared through the hallways of a Peshawar, Pakistan, school. Then, 14-year-old student Ahmed Faraz recalled, one of them changed the narrative. 'A lot of the children are under the benches,' a Pakistani Taliban member said, according to Ahmed. " 'Kill them.' "

By the time the hours-long siege at Army Public School and Degree College ended early Tuesday evening, at least 137 people -- most of them children -- were dead, Khyber Pakhtunkhwa province Information Minister Mushtaq Ghani said. More than 100 were injured, many of them suffering gunshot wounds.

The death toll does not include the attackers. Mohammed Khurrassani, spokesman for Tehreek e Taliban Pakistan, or Pakistan Taliban, said the six militants scaled the school's walls around 10 a.m. (midnight ET), intent on killing older students there.

These Taliban had "300 to 400 people ... under their custody" at one point, Khurrassani said.
