Kirkuk, Iraq - A series of apparently coordinated bombings targeting Shiite places of worship, or husseiniyahs, in north Iraq killed at least eight people and wounded 33 on Friday, a medical official said.

A car bomb targeted the Khezal al-Tamimi husseiniyah in central Kirkuk at about 12:55 pm (0955 GMT), followed by a bombing at Imam Ali husseiniyah in the city's northeast, and three bombings at Al-Mustafa husseiniyah in south Kirkuk, security and medical officials said.

Sadiq Omar Rasul, the head of Kirkuk health department, told AFP that eight people were killed and 33 wounded in the attacks.

An AFP correspondent saw the burned bodies of two children and dozens of burned-out cars at Al-Mustafa husseiniyah.

Hadi Qanbar, who had been praying at Al-Mustafa husseiniyah, said that worshippers were told about the attack on Khezal al-Tamimi and began to leave.

“But when we left, explosions happened one after another,” he said. “We do not know why we were targeted.”

Azhar Kamal, who was also at Al-Mustafa husseiniyah, said: “We put the blood of the victims on the hands of the prime minister, and we ask him to protect the people of Kirkuk.”

Hassan Hussein, who was at Khezal al-Tamimi at the time of the attack, said the explosion happened behind the husseiniyah.

“We saw our brothers and friends killed and wounded by this explosion,” he said.

Khezal al-Tamimi husseiniyah is the site of powerful Shiite cleric Moqtada al-Sadr's main office in Kirkuk.

Violence in Iraq is down dramatically from its peak between 2006 and 2008, but attacks remain common with 278 people killed in August, according to an AFP tally based on reports from security officials and medics. - Sapa-AFP
