MOSUL, Iraq, June 10 (Xinhua) -- Armed militant groups took control of more parts of Iraq's second largest city of Mosul as fierce clashes continued for the fifth day, a police source said on Tuesday.
On late Monday, hundreds of gunmen armed with heavy machine guns on vehicles, rocket-propelled grenades and assault rifles attacked the headquarters of the provincial government and fierce fighting flared in the area, a police source told Xinhua on condition of anonymity.
Governor Atheel al-Nujaifi, a brother of Iraqi Speaker Osama al- Nujaifi, was trapped by the overnight fighting around the governorate building, but managed to escape later, the source said.
On Tuesday, the armed groups gained more ground and expanded the areas which earlier were under their control in western Mosul, some 400 km north of the Iraqi capital of Baghdad, the source added.
Since Friday morning, bloody clashes broke out between the Iraqi security forces and hundreds of gunmen who took control of several neighborhoods in western part of Mosul.
Nineveh is a Sunni-majority province and its capital Mosul has long been a stronghold for insurgent groups, including al-Qaida militants, since the U.S.-led invasion of Iraq in 2003.
