Iraqi military soldiers backed by thousands of tribal fighters have repelled a fresh assault by ISIL terrorists on the strategic town of Haditha, Press TV reported.
The attack on Haditha in Anbar Province began after the ISIL fired several rockets at military outposts in the troubled region on Saturday.
Reports say the government forces killed more than three dozen ISIL terrorists in the fierce fighting in the western town.
A senior Iraqi army commander says 4,000 volunteers are being airlifted to Ramadi, the capital of the western Anbar Province.
Security sources say volunteer forces are being sent to Ramadi to help government forces there gain the upper hand in battles against the ISIL militants.
This comes as parts of Ramadi are under the control of the ISIL also known as Daesh. The Takfiri group is also controlling the city of Fallujah in Anbar Province.
Latest reports say violent clashes have erupted in the central province of Diyala as security forces fought back against militants across the volatile region.
Reports say the ISIL's advance has been slowed down as Iraqi military and volunteer forces have begun engaging militants on several fronts.
The majority of the volunteer forces are Shia Muslims and Sunni tribesmen answering a call from top Shia cleric Ayatollah Ali al-Sistani. Senior Muslim clerics have condemned the ISIL atrocities, including mass executions and rape.
The terrorist group has links with Saudi intelligence and it is believed that it is being indirectly supported by the Israeli regime.
Iraqi Premier Nouri al-Maliki has vowed that the country's security forces would confront the Takfiri terrorists. The US and its regional allies - especially Saudi Arabia, Qatar and Turkey - are supporting the militancy in Iraq.
