BAGHDAD (Reuters) - Iraqi forces launched a final assault on Wednesday to capture the town of Hawija, one of two pockets of territory in Iraq still under Islamic State control, the country's military said in a statement.
Iraqi state TV broadcast live footage showing the area covered by thick black smoke, rising from oil wells torched by the militants as a tactic to prevent air detection. Hawija is located near the oil city of Kirkuk, in northern Iraq.
The offensive on Hawija is being carried out by U.S.-backed Iraqi government troops and Iranian-trained and armed Shi'ite paramilitary groups known as Popular Mobilisation.They began moving on the town of Hawija two days after capturing the Rashad air base, 30 km (20 miles) to the south and used by the militants as a training and logistics site.
Iraq launched an offensive on Sept. 21 to dislodge Islamic State from Hawija and surrounding areas where up to 78,000 people could be trapped, according to the United Nations.
Iraqi security officials say the militants are preventing some residents from leaving, while others are afraid of escaping towards government forces because of explosives that might have been laid by Islamic State around the town.
The other area of the country still under the control of the militant group is a stretch of land along the Syrian border, in western Iraq, including the border town of al-Qaim.
The militants also hold the Syrian side of the border at al-Qaim, but the area under their control is shrinking as they retreat in the face of two different sets of hostile forces -- a U.S.-backed, Kurdish-led coalition, and Syrian government troops with foreign Shi'ite militias backed by Iran and Russia.
Islamic State's cross-border "caliphate" effectively collapsed in July, when U.S.-backed Iraqi forces captured Mosul, the group's de facto capital in Iraq, in a gruelling battle which lasted nine months.
The militants' leader Abu Bakr al-Baghdadi, who declared the caliphate from Mosul in mid-2014, released an audio recording last week that indicated he was still alive. He called on his followers to keep up the fight despite the setbacks.
