Militants wearing suicide vests and firing automatic rifles stormed a Pakistani police academy in the southwestern city of Quetta overnight killed at least 59 people and wounded another 117, mostly police cadets and recruits.

There were conflicting claims of responsibility on Tuesday for the attack. The Islamic State group took responsibility, as did a little known Pakistani Taliban faction known as the Hakimullah group. Militant attacks have in recent years claimed the lives of hundreds of people, including many schoolchildren.
