At least eight people were killed after a suicide bomber rammed a vehicle into an intelligence headquarters in Baghdad.

A suicide bomber rammed a vehicle into an intelligence headquarters in Baghdad on Saturday, killing at least eight people, police and medical sources said.

The attack came a day after Shiite militiamen machinegunned 68 Sunni worshipers at a village mosque in Diyala Province, raising the prospect of revenge attacks as politicians try to form a government capable of countering Islamic State militants.

Following the mosque attack, two major sunni parliamentary blocs pulled of talks on forming a new Iraqi cabinet, setting up a challenge for prime minister-designate Haider al-Abadi.

An advance by Islamic State of Iraq and Syria (ISIS) militants group through northern Iraq has alarmed the Baghdad government and its Western allies and drawn airstrikes in Iraq for the first time since the withdrawal of American troops in 2011.

Although the air campaign has caused a few setbacks for Islamic State, they do not address the wider problem of sectarian warfare which the group has fueled with attacks on Shiites.

Bombings, kidnappings and execution-style shootings occur almost daily, echoing the dark days of 2006-2007, the peak of a sectarian civil war.
