'The special forces have stormed in': Iraqi forces enter Mosul, main city fight ahead

Iraq's special forces entered the outskirts of Mosul on Tuesday, taking the state television building and advancing despite fierce resistance by ISISfighters who hold the city, an Iraqi general said.

It was the first time in over two years that Iraqi troops have set foot inside the city, Iraq's second largest. The advance could be the start of a grueling and slow operation for the troops, who will be forced to engage in difficult, house-to-house fighting in urban areas that is expected to take weeks, if not months.

Troops entered Gogjali, a neighbourhood inside Mosul's city limits, and later the borders of the more built-up Karama district, according to Maj. Gen. Sami al-Aridi of the Iraqi special forces. As the sun went down, a sandstorm blew in, reducing visibility to only 100 metresand bringing the day's combat to an end.

"Daesh is fighting back and have set up concrete blast walls to block off the Karama neighbourhood and our troops' advance," al-Aridi said, using the Arabic acronym for ISIS, also known asthe Islamic State in Iraq and Syria. Bombs have been laid along the road into the city, he added.

Later, al-Aridi said the troops had taken the nearby state television building, the only one in the province, and that heavy fighting broke out when they tried to continue further in to built-up areas. An official casualty report has yet to be given, but officers mentioned one dead and one wounded.

Mosul is the final ISIS urban bastion in Iraq, the city from which it drove out a larger but demoralized Iraqi army in 2014 and declared a "caliphate" that stretched into Syria. Its loss would be a major defeat for the jihadis, but with the closest Iraqi troops still some 10 kilometres from the city centre, much ground remains to be covered.

Tuesday's battle opened up with Iraqi artillery, tank and machine-gun fire on ISISpositions on the edge of Gogjali, with the extremists responding with guided anti-tank missiles and small arms in an attempt to block the advance. Airstrikes by the U.S.-led coalition supporting the operation added to the fire hitting the district.

Spokesman Col. John Dorrian said that the U.S.-led coalition, which co-ordinates all its attacks with the Iraqis, has been observing the battlefield and has noted that ISIS forces can no longer move in large numbers.

"And when we see them come together where there are significant numbers we will strike them and kill them," he said during a televised press conference with Iraqi forces in Qayara, south of Mosul. Concerns over civilian casualties have led to air operations using precision munitions only, he added.

In a statement, the coalition said that a day earlier it had launched six strikes in the Mosul area, destroying 10 vehicles, including one carrying explosives, as well as a bomb-making facility. It also said it damaged 20 vehicles and a tunnel.

White flags hung in nearby town

From the nearest village east of Mosul, Bazwaya, smoke could be seen rising from buildings in Gogjali, where shells and bombs had landed. ISIS fighters also lit special fires to produce dark smoke in order to obscure the aerial view of the city.

Inside the village, white flags still hung from some buildings, put up a day earlier by residents eager to show they would not resist the Iraqi forces' advance. Some residents stood outside their homes, and children raised their hands with V-for-victory signs.

The families, estimated to number in the hundreds, will be evacuated from the village to a camp for displaced persons, according to Brig. Gen. Haider Fadhil of the Iraqi special forces.

As the fighting raged, several of the newly displaced from Bazwaya could be seen carrying white flags and driving a herd of some 150 sheep toward the camp.

Emad Hassan, 33, a former policeman, said he had come to Bazwaya when the operation started in order to flee the ISISfighters.

"When I knew the security forces were serious about liberating Mosul, I came here," he said. "Daesh was preventing families from moving toward the security forces and ordered them into the city centre, but I refused and stayed."

For over two weeks, Iraqi forces and their Kurdish allies, Sunni tribesmen and Shiamilitias have been converging on Mosul from all directions to drive ISIS from the city.

Iraqi forces have made uneven progress in closing in on the city. Advances have been slower to the south, with government troops still 35 kilometresaway. To the north are Kurdish forces and Iraqi army units, and Shiamilitias are sweeping toward the western approach in an attempt to cut off a final ISIS escape route.

The Shiaforces, Iran-backed troops known as the Popular Mobilization Units, are not supposed to enter Mosul, given concerns that the battle for the Sunni-majority city could aggravate sectarian tensions.

Just behind the eastern front line, the army's ninth division has moved toward Mosul on the path cleared by the special forces, and was now approximately threekilometresfrom its eastern outskirts.

The U.S. military estimates ISIS has 3,000-5,000 fighters in Mosul and another 1,500-2,500 in its outer defensive belt. The total includes about 1,000 foreign fighters. They stand against an anti-ISIS force that including army units, militarized police, special forces and Kurdish fighters, totals over 40,000 men.

1,792 killed in Iraq in October

According to a video published online by ISIS, life was normal inside the Karama district a day earlier. Released by its Aamaq news agency, the footage from Karama shows residents insisting that life is normal and that "no apostates or Shias" had entered the city

"We hear the thud of the bombs fired by our brothers at the apostates," said a bearded man in a wheelchair, speaking from a market street where taxis and shoppers passed by unimpeded.

As the Mosul offensive has pressed on, bombings have continued in the capital, Baghdad part of sustained ISIS efforts to destabilize the country. Dozens have been killed since the push on Mosul started in apparent retaliation attacks, mostly claimed by ISIS.

Violence is still rampant across the country, with killings worsening in October, the United Nations said. In a monthly report released by the UNAssistance Mission for Iraq, it said 1,792 people were killed in violence in Iraq in October, up from 1,003 the previous month. 1,120 of the dead were civilians.

The worst-hit city is Baghdad with 268 civilians killed and 807 wounded, while the militant-held Ninevah province comes next, with 566 killed and 59 wounded. The UNdidn't say whether the Mosul operation was directly related to the casualties in Ninevah, its surrounding province.

Also Tuesday, Kurdish authorities detained a Japanese freelance journalist covering the fighting. Japanese government spokesman Yoshihide Suga said in Tokyo that "we are aware that he is currently being detained" and that Japan is trying to determine why.

Japan's Kyodo News agency says that journalist Kosuke Tsuneoka was reporting on the battle to recapture the city of Mosul from ISIS. Kyodo reported he is being held by the Kurdish fighters known as the peshmerga.
