Iraqi Peshmerga storm IS-held town of Bashiqa
Iraqi Kurdish peshmerga forces stormed an Islamic State-held town northeast of Mosul on Monday, clearing a pocket of militants outside the city while Iraqi troops wage a fierce urban war with the group in its eastern districts.
In Bashiqa, some 15km from Mosul, a 2,000-strong peshmerga force sought to drive out the militants from the town, which lies on the Nineveh plains at the foot of a mountain.
Artillery pounded the town before the Kurdish peshmerga and US special forces entered the town in armoured vehicles, Humvees and on foot.
"Our aim is to take control and clear out all the Daesh (Islamic State) militants," Lieutenant-Colonel Safeen Rasoul told Reuters as the operation began. "Our estimates are there are about 100 still left and 10 suicide cars."
Islamic State militants have sought to slow the offensive on their Mosul stronghold with waves of suicide car bomb attacks. Iraqi commanders say there have been 100 on the eastern front and 140 in the south.
A top Kurdish official told Reuters on Sunday IS had also deployed drones strapped with explosives, long-range artillery shells filled with chlorine gas and mustard gas, and snipers.
As a Peshmerga column moved into Bashiqa on Monday, a loud explosion rocked the convoy, and two large plumes of white smoke could be seen just 15m away. A Peshmerga officer said two suicide car bombs had tried to hit the advancing force.
"They are surrounded... If they want to surrender, OK. If they don't, they will be killed," said Lieutenant-Colonel Qandeel Mahmoud, standing next to a Humvee, supported by a cane he said he has needed since he was wounded in the leg by two suicide car bombers four months ago.
Armed US soldiers, part of a 5,000-strong force Washington says is advising and supporting the Iraqi offensive, were accompanying the Peshmerga in Bashiqa through streets lined by rows of damaged houses, some with entire floors collapsed.
Fighting was intense and at one stage a convoy of 40 vehicles was held up by a single Islamic State sniper.
Kurdish military authorities later said the peshmerga were carrying out house-to-house searches in the town.
In eastern districts of Mosul, which Iraqi special forces broke into last week, officers say militants melted into the population, ambushing and isolating troops in what the special forces spokesman called the world's "toughest urban warfare".
Mosul, the largest Islamic State-controlled city in either Iraq or Syria, has been held by the group since its militants drove the army out of northern Iraq in June 2014. The campaign to retake it is the most complex military operation in Iraq since the 2003 US invasion which toppled Saddam Hussein.
An alliance of US-backed Kurdish and Arab groups on Sunday launched a campaign to close in on Raqqa in Syria, where Islamic State has been dug in for nearly three years, with an assault on territory about 50km to the north which they have dubbed "Euphrates Anger".
Twin offensives on Raqqa and Mosul could bring to an end the caliphate declared by Islamic State leader Abu Bakr al-Baghdadi from the pulpit of a Mosul mosque in 2014.
Baghdadi, whose whereabouts are unknown but who is believed to be in northern Iraq close to the Syrian border, has told his followers not to retreat in the "total war" with their enemies.
They have lost ground on all fronts, however, despite waging a fierce defence.
One Mosul resident told Reuters by phone he had seen 30 bodies and about 40 seriously wounded people brought into Salam Hospital, used by Islamic State to treat its casualties.
Elsewhere in the city, three residents said the Islamic State presence across Mosul was far less visible in recent days, but cautioned that the militants had dropped out of view before and then reappeared en masse.
Others said there were signs that some of Islamic State's local supporters had fled, including one family whose son joined the militants when they took over Mosul. The family fled without warning, and two days later Islamic State put up signs on their empty house which read: "Property of Islamic State".
Some were frustrated and frightened by what they said was the slow army advance. "We're asking ourselves what's happening? We were expecting the Iraqi forces to reach us much quicker," he said.
To the south of Mosul, security forces said they had recaptured and secured the town of Hammam al-Alil from Islamic State militants, who they said had kept thousands of residents as human shields as well as marching many others alongside retreating militants towards Mosul as cover from air strikes.
The United Nations has warned of a possible exodus of hundreds of thousands of refugees from a city which is still home to up to 1.5 million people. So far 34,000 have been displaced, the International Organisation for Migration said.
Security forces on the southern front have continued their advance, reaching within 4km of Mosul's airport, on the southern edge of the city and on the western bank of the Tigris River which runs through its centre.
To the north, a military statement said the army's 16th Infantry Division had also recaptured the village of Bawiza and entered another area, Sada, on the city's northern limits, further tightening the circle of forces around Islamic State.
Shia militias known as Popular Mobilisation forces are also fighting to the west of Mosul to seal the routes to the Islamic State-held town of Tal Afar and its territory in neighbouring Syria, to prevent any retreat or reinforcement.
