Two Sunni mosques in the Iraqi city of Kirkuk were strewn with rubble and bloodstains after they were targeted in a twin roadside bombing late on Tuesday (July 23).
At least seven people were killed and more than 30 others were wounded as worshipers gathered for special extended evening prayers in the ethnically mixed city.
One bomb was detonated outside the Omar bin Abdulaziz mosque, while another hit the nearby mosque of Al-Saliheen in a southern district of Kirkuk, about 250 km (155 miles)
north of the capital Baghdad.
The latest violence is part of a sustained campaign of militant attacks since the beginning of the year.
Concerns have been raised that a wider conflict is yet to come in a country where ethnic Kurds, Shi'ite and Sunni Muslims have yet to find a stable power-sharing compromise.
