At least two people were killed after a bomb exploded in a market on the outskirts of the Pakistani city of Quetta on Tuesday, Pakistan officials told media.

Mir Ziaullah Longove, the provincial home minister, described the bombing as an “act of terrorism” by the “enemies of Pakistan,” and said an emergency has been declared.

No one immediately claimed responsibility for the blast.
