Heavily-armed militants wearing suicide vests stormed a police academy in Quetta, killing at least 61 people and wounding at least 117, in the deadliest attack on a security installation in the country's history,on tuesday.
Three gunmen burst into the sprawling academy, targeting sleeping quarters home to some 700 recruits, and sent terrified young men aged between 15 and 25 fleeing.
Communication intercepts showed the attack was carried out by Al-Alimi faction of the Lashkar-i-Jhangvi (LJ) militant group, IG Frontier Corps (FC) Major General Sher Afgan said.
Separately, the militant Islamic State group claimed responsibility for the attack, according to the group's Amaq news agency. The training centre houses at least 600 cadets.
Most of the deaths were caused when two of the attackers blew themselves up. The third was shot dead by Frontier Corps (FC) troops.
