Islamic State fighters executed 12 Shiite militiamen north of Baghdad after heavy fighting for control of a rural village security sources said on Sunday.
Army and police officials said Iraqi security forces and the Shiite militia fighters launched an attack on Friday against Islamic State militants on Tal Al-Thahab near the town of Balad 80 km north of the Iraqi capital.
They managed to drive the militants from their base in Tal Al-Thahab police station on Friday but hours later the Islamic State fighters returned and surrounded it trapping dozens of security forces and militiamen inside.
'Supporting troops with cover from army helicopter reached the area and managed to break the siege. We have confirmation from our sources that 12 volunteer fighters were executed on Saturday by terrorists' said an army intelligence officer on condition of anonymity.
Balad's mayor Amir Abdul Hadi confirmed that some of the Shiite militiamen were executed by Islamic State near Balad and others were missing after Friday's battle but said he did not have details. Officials said 10 militiamen were missing.
Sources at Balad hospital said they had received at least six bodies of militia fighters believed to have been killed in the first wave of fighting on Friday.
Balad which houses a shrine to a revered Shiite imam is one of several towns north of Baghdad which has seen heavy fighting between Islamic State fighters who control large parts of north and west Iraq and Iraqi security forces and pro-government Shiite militia.
Security and local officials said more Shiite militia fighters were gathering in Balad to try to drive out Islamic State militants from areas surrounding the town.
'We have asked the residents to stock food and basic material to prepare for an imminent military operation against the terrorists around Balad' one official said.
In the town of Tarmiya between Balad and Baghdad militants detonated a car bomb overnight at a security checkpoint before attacking with guns. Five police and three civilians were killed security and medical sources said.
