(CNN) ISIS has claimed responsibility for an attack which killed four Christians in Pakistan's Balochistan province on Easter Monday.

An Islamic State press statement released on Tuesday said that a "covert unit" of ISIS militants "managed to target a number of the combatant Christians."

The statement adds that the militants "shot them with a pistol, which resulted in the killing of four of them, and all praise is due to Allah"

The shooting, which targeted a single family, occurred in the western city of Quetta, the provincial capital.

Armed men opened fire at a rickshaw carrying the family of three who were returning home from a bazaar at around 6:45 p.m. (9.45 a.m. ET) local time. The men fled on a motorcycle.
