Dozens of students killed in attack
Washington CNN —  

The school attack that left more than one hundred children dead in Pakistan demonstrates the “depravity” of the terrorists responsible, President Barack Obama said in a statement Tuesday.

Condemning the school siege in Peshawar, Obama said that “By targeting students and teachers in this heinous attack, terrorists have once again shown their depravity.”

“Our hearts and prayers go out to the victims, their families, and loved ones,” Obama wrote, adding later the U.S. government was committed to working with Pakistan to combat terrorists.

Taliban militants massacred at least 126 people – mostly children – at the Army Public School in the northwest part of Pakistan on Tuesday, the worst terror attack in the country since 2007.

Secretary of State John Kerry, speaking in London, said the culprits behind the siege served a “dark and almost medieval vision.”

Calling images emerging from the scene “gut wrenching,” Kerry said the attackers had turned a “house of learning into a house of unspeakable horror.”

“This act of terror angers and shakes all people of conscience,” Kerry said during his news conference.

The U.S. has worked to combat militants in Pakistan though unmanned drones, a program which ramped up under Obama.
