Officials say gunmen attacked an Islamic religious gathering in the southern Pakistani port city of Karachi, killing eight people and wounding at least 10 more.
Officials said the gunmen first threw grenades at the building where a Sufi cleric was receiving his followers, and then opened fire.
No group has claimed responsibility for the attack, which took place late on February 9.
Pakistan is 95 percent Muslim, and the majority practice Sufi-influenced Islam.
But their shrines and followers have come under attack in Pakistan by Sunni Muslim militants who don't consider them to be true believers.
