The death toll from a Taliban attack on a school in Peshawar, Pakistan, has risen to 145, making it the deadliest single attack in the group’s history. Over an eight-hour period, a group of Taliban gunmen killed 132 schoolchildren, 10 staff and three soldiers. The Taliban has said it carried out the killings in retaliation for Pakistani military attacks on Taliban families in North Waziristan. Secretary of State John Kerry condemned the school massacre.

John Kerry: “The images are absolutely gut-wrenching—young children carried away in ambulances, a teacher burned alive in front of the students, a house of learning turned into a house of unspeakable horror. And Prime Minister (Nawaz) Sharif said, 'These are my children, and it is my loss.' Well, this morning, wherever you live, wherever you are, those are our children, and this is the world’s loss.”
