Kurdish Peshmerga forces launched a fresh attack on so-called Islamic State forces today as part of a campaign to capture Mosul, the militants' de facto capital in Iraq, Kurdish officials said.
The advance began after heavy shelling and air strikes by a United States-led coalition against IS forces. The militants fought back, firing mortars at the advancing troops and detonating at least two car bombs.
A Peshmerga commander said a dozen villages had been taken from the ultra-hardline Sunni militants as Kurdish forces headed towards Gwer, the target of the operation, 40 km southeast of Mosul.
Repairing a bridge that the militants destroyed in Gwer would allow the Peshmerga to open a new front around Mosul. The bridge crosses the Grand Zab river that flows into the Tigris.
IS said in a statement on its Amaq news service that two car bombs driven by suicide fighters were detonated in one of the villages to block advancing Kurdish forces, causing casualties among the Peshmerga.
Authorities in autonomous Kurdistan gave no toll for the fighting, other than confirming the death of a Kurdish TV cameraman and the injury of another journalist.
Clouds of black smoke rose from the scene of fighting and dozens of civilians fled in the direction of Peshmerga lines, brandishing white flags.
The Iraqi army and the Peshmerga forces of the Kurdish self-rule region are gradually taking up positions around Mosul, 400 km north of the capital Baghdad.
It was from Mosul's Grand Mosque in 2014 that IS leader Abu Bakr al-Baghdadi declared a "caliphate" spanning regions of Iraq and Syria.
Mosul is the largest urban centre under the militants' control, and had a pre-war population of nearly two million.
Its fall would mark the effective defeat of IS in Iraq, according to Prime Minister Haider al-Abadi, who has said he aims to retake the city this year.
The Iraqi army is trying to close in from the south. In July it captured the Qayyara airfield, 60 km south of Mosul, which is to serve as the main staging post for the anticipated offensive.
The Peshmerga operation was "one of many shaping operations that will also increase pressure on ISIL in and around Mosul," said an official from the Kurdistan Regional Security Council, using another acronym to refer to IS.
Once the fighting intensifies around Mosul, up to one million people could be driven from their homes in northern Iraq, posing "a massive humanitarian problem", the International Committee of the Red Cross forecast last month.
More than 3.4 million people have already been forced by conflict to leave their homes across Iraq, taking refuge in areas under control of the government or in the Kurdish region.
