BAGHDAD, Iraq (CNN) -- At least nine people were killed and at least 30 were wounded Friday in a suicide attack targeting Sunni Muslim worshipers at a mosque in northern Iraq, an Interior Ministry official said.
It occurred in Tal Afar, a largely Turkmen city populated by Shiites and Sunnis in Nineveh province -- where violence has been persistent in recent months. The incident occurred at the end of Friday prayers.
The ministry official said that the attacker was wearing an explosive vest and carrying a weapon when he went inside the mosque. He opened fire, killing the mosque imam and few others before he blew himself up.
