Taliban militants stormed a school in northwest Pakistan on Tuesday, leaving scores of students dead.
Quoting Pakistani officials, multiple media outlets say the death toll is at least 140, including at least 80 students in grades 1 through 10.
A little before 8 p.m. local time, police announced that the operation had ended after the gunmen were killed. Security personnel, police official Abdullah Khan told the AFP, were now in the process of sweeping the rest of the building.
