Iraqis in the city of Kirkuk inspect damage to a local Shi'ite mosque.
A car bomb detonated here on Monday, killing at least one civillian and wounding 16 others.
(SOUNDBITE) (Arabic) EYEWITNESS, ABU AHMED, SAYING:
"This is a mosque, Allah's house. Even the holy book, the Koran was burnt. This is a mosque, not the headquarters of a party in which there is an official to be targeted, this is Allah's house. I don't know what religion they believe in?"
The blast was part of a string of coordinated attacks.
Elsewhere in the city, a motorbike bomb detonated next to a police patrol.
Mortar rounds also landed in areas populated by Shi'ites and Turkmen.
The attacks were the latest in a wave of violence that's stoking sectarian tensions and challenging the country's Shi'ite Muslim Prime Minister Nuri al-Maliki.
No group has claimed responsibility for Monday's attacks.
But Iraq's local Al-Qaeda wing has been behind similar, deadly attacks on Shi'ite targets in Baghdad in recent days.
