At least 41 police trainees were killed and more than 100 others wounded on Monday when terrorists detonated explosives and opened fire at a training center in Quetta, Pakistan.

The six gunmen belonged to Lashker-e-Jhangvi, an Islamic militant group affiliated with al Qaeda, according to Maj. Gen. Sher Afgan, chief of the paramilitary Frontier Corps. Police trainees and paramilitary troops made up the majority of those injured in the attack.
