The Islamic State and a Pakistani Taliban faction based in Quetta both claimed responsibility for yesterday’s suicide attack at a police academy in Quetta that killed at least 60 people and wounded more than 120. Pakistani officials claim another jihadist group, Lashkar-e-Jhangvi al Alami carried out the assault.

Pakistan’s Frontier Corps said that Lashkar-e-Jhangvi al Alami executed the attack and claimed that the suicide assault team communicated with handlers based in Afghanistan.

The Islamic State’s Khorasan province, which operates in South Asia, also took responsibility for the attack. In a statement released on Amaq News Agency, an Islamic State propaganda arm, the group named three attackers: Obaidah al Khorasani, Omar al Khorasani, and Talha al Khorasani, and also released a photograph of the fighters.

The Pakistani Taliban and the Islamic State have competed over claiming responsibility for mass-casualty attacks in the past. Both groups claimed credit for the Aug. 8, 2016 suicide attack at a hospital Quetta that killed scores of people.
