ISIL fighters have launched several fierce counterattacks against Iraqi forces on the eastern outskirts of Mosul city, underscoring the intense battle ahead as government troops and their allies push into densely populated neighbourhoods. An ISIL suicide car bomber targeted Iraqi troops in the city's eastern Qadisiya neighbourhood early on Saturday, setting off heavy fighting that involved mortar rounds, gunfire, and rocket-propelled grenades. Iraqi officers told the AFP news agency fighting was also under way in the adjoining Arbajiya area. "The fighting is intense this morning. We're trying to fortify our positions in Arbajiya before continuing our attack into al-Bakr," Colonel Muntadhar Salem of the counterterrorism unit said.
