Two suicide bombers killed at least five people and wounded more than 20 in an attack on a Shiite mosque in the northern Iraqi city of Kirkuk on Sunday, police and medical sources said.

It was the first such attack since the central Iraqi government in Baghdad seized Kirkuk last month from Kurdish forces that had controlled the oil city of a million people for three years.

Acting Kirkuk Gov. Rakan Saeed appealed to Iraqi Prime Minister Haider al-Abadi after a meeting of the provincial security panel to send more troops to secure the city.
