WASHINGTON (AP) — President Barack Obama is condemning what he calls a “heinous attack” on a Pakistani school.

Obama says terrorists are once again showing their depravity with the shooting spree that killed 126 in the city of Peshawar.

Taliban gunmen stormed the Army Public School Tuesday morning in the worst attack in Pakistan in years. Most of the victims were students in the first through 10th grades.

Obama says the U.S. stands with Pakistan in its efforts to fight extremism and promote peace. He offered prayers to the victims and their loved ones.
