Gunmen have attacked a Sunni Muslim mosque in the Pakistani port city of Karachi, killing one person and wounding two others, including a prayer leader.
Police officials say two men opened fire at the Mohammadi Mosque during morning prayers Wednesday.
Officials say the gunmen fled the scene and have not been caught.
Pakistani police are investigating the shooting, and say they do not know if it was a terrorist attack.
Traditional rivalries between Shiite and Sunni Muslims have sparked a wave of sectarian attacks in Pakistan in recent months.
