BAGHDAD (Reuters) - Iraqi security forces and Shi'ite militia fighters struggled to advance on Saturday into the two towns of al-Alam and al-Dour near Tikrit, their progress slowed by fierce defense from Islamic State militants.
"We are facing a strong resistance from terrorist groups and we are trying to surround Daesh inside al-Alam and al-Dour and cut all supply routes for them," said al-Alam mayor Laith al-Jubouri, referring to the Islamic State fighters.
Army and militia fighters entered the southern and eastern parts of al-Dour on Friday. Commanders said at the time that the town had been completely recaptured, but officials said only parts of it had been retaken.
