Fresh clashes over Tikrit

Al-Huriya News Agency - Iraqi government forces are continuing an offensive to retake the northern city of Tikrit from Sunni rebels.

Aircraft have struck at rebel positions and clashes have broken out in various parts of the city, witnesses and officials have said. Troops had reportedly pulled back to the nearby town of Dijla as Saturday's initial offensive met stiff resistance.

The city of Tikrit was captured by Sunni rebels on 11 June as they swept across large parts of northern Iraq. "The security forces are advancing from different areas", Lt-Gen Qassem Atta told journalists. "There are ongoing clashes."
