Battle for Mosul: The story so far Battle for Mosul: The story so far
(8 days later)
Hundreds of thousands of civilians have fled the northern Iraqi city of Mosul as government security forces continue their military offensive to reclaim the city from so-called Islamic State (IS). Iraqi government forces are on the verge of reclaiming the last area of western Mosul from so-called Islamic State, after an eight-month offensive to drive the jihadist group from the city.
Iraqi army forces have retaken western Mosul and encircled IS fighters in the Old City, a narrow maze of alleyways and location of the Great Mosque of al-Nuri. Iraqi army forces, who cleared the eastern half of Mosul in January, have encircled fighters in a small pocket of the densely-populated Old City. Commanders say they expect to declare victory imminently.
The mosque was destroyed on 21 June, blown up by IS according to Iraqi forces, to slow the advance of pro-government troops. IS claimed the mosque was destroyed in a US air raid. Hundreds of thousands of civilians have fled what was once Iraq's second largest city since October. But the UN estimates that up to 20,000 civilians may still be trapped there, and warned that some are being used as human shields by IS.
The ancient mosque was where in July 2014 IS leader Abu Bakr al-Baghdadi demanded allegiance, in his first and only public appearance, following the declaration days earlier of a "caliphate". What's happening in Mosul?
Thousands of Iraqi security forces, Kurdish Peshmerga fighters, Sunni Arab tribesmen and Shia militiamen, assisted by US-led coalition warplanes and military advisers, are involved in the Mosul offensive, which was launched on 17 October 2016. Thousands of Iraqi security forces, Kurdish Peshmerga fighters, Sunni Arab tribesmen and Shia militiamen, assisted by US-led coalition warplanes and military advisers, are involved in an offensive to recapture Mosul.
The government announced the full "liberation" of eastern Mosul in January 2017. The operation was launched on 17 October 2016 after the rapid advance of IS militants across Iraq and Syria in 2014.
Shifting territorial control The offensive's progress was initially swift, with forces advancing from the north, south and east, seizing outlying towns and villages despite strong resistance. But progress slowed as troops entered the city limits, with snipers, suicide bombers and shellfire targeting them.
More than 580,000 civilians have fled the city since October 2016, according to the Iraqi government. The Iraqi government announced the full "liberation" of eastern Mosul in January 2017. But the west of the city presented a more difficult challenge, with its narrow, winding streets.
Most have taken refuge in nearby camps and reception centres. Others have gone to stay with relatives and friends. How much territory does IS hold?
Following the recapture of eastern Mosul in January, there was deep concern for thousands of people remaining in the east of the city, with food supplies reported to be very low and clean drinking water in short supply. According to analysis by IHS Conflict Monitor, IS fighters have lost a significant amount of territory since the regional offensive began.
The UN said in late January that almost half of all the casualties in Mosul were civilians. At least 2,014 have been killed and 1,516 injured across Nineveh province since October 2016. However, their losses slowed when Iraqi government forces met stiff resistance in the city of Mosul.
Lt Gen Stephen Townsend, the coalition's task force commander, described the recapture of eastern Mosul as a "monumental achievement" for the Iraqi people, but warned there was "still a long way to go" before IS was eliminated from Iraq. But by the beginning of July, Iraqi forces had removed IS from all but a pocket of territory in the western half of Mosul, where militants are making their last stand.
It took from mid-October until 8 January 2017 for Iraqi forces to advance as far as the River Tigris and another two weeks to gain full control of the eastern side of Mosul. There may be only dozens of IS fighters holed up in the area on the banks of the Tigris, but the densely-packed housing and narrow alleyways have enabled them to target the advancing troops with snipers and suicide bombs.
Territorial loss Contradictory reports have made it difficult to track the progress of the government offensive on the ground.

Satellite images have revealed extensive damage to Mosul's infrastructure, buildings and archaeological sites - in particular to the city's airport and bridges.Satellite images have revealed extensive damage to Mosul's infrastructure, buildings and archaeological sites - in particular to the city's airport and bridges.
Mosul airport The jihadists constructed barricades across key routes and razed buildings so fighters could see the advancing troops.
Most recently, the ancient Great Mosque of al-Nuri, where IS leader Abu Bakr al-Baghdadi demanded allegiance after declaring a "caliphate", was blown up by IS, according to Iraqi forces. IS claims the mosque was destroyed in a US air raid.
Imagery, released by US geopolitical intelligence company Stratfor in October 2016, showed how IS fighters sabotaged much of the city's airport, with wide trenches carved into it and rubble placed along their lengths.Imagery, released by US geopolitical intelligence company Stratfor in October 2016, showed how IS fighters sabotaged much of the city's airport, with wide trenches carved into it and rubble placed along their lengths.
The images also show how coalition airstrikes, aimed at destroying key IS positions and assets, caused damage to Mosul's sugar factory - a facility kept in action by the militants.
Imagery also revealed how the jihadists constructed multiple barricades across key routes into the city, including north of the airport.Imagery also revealed how the jihadists constructed multiple barricades across key routes into the city, including north of the airport.
The barriers have been made out of concrete blocks and other rubble, Stratfor's analysis says, possibly from the walls of destroyed buildings. The barriers were made out of concrete blocks and other rubble, Stratfor's analysis said, possibly from the walls of destroyed buildings.
Mosul's bridges Meanwhile, coalition air strikes destroyed all bridges linking the east and west of the city across the Tigris river, with the aim of limiting the jihadists' ability to resupply or reinforce their positions in the east.
All bridges linking the east and west of the city, across the Tigris river, were also destroyed.
In the centre of the city, four of the five main bridges were put out of action in October and November by coalition air strikes, with the aim of limiting the jihadists' ability to resupply or reinforce their positions in the east.In the centre of the city, four of the five main bridges were put out of action in October and November by coalition air strikes, with the aim of limiting the jihadists' ability to resupply or reinforce their positions in the east.
The Old Bridge - the only remaining route open to vehicles in the centre of the city - was disabled in a US-led coalition air strike at the end of December.

Iraqi forces have since recaptured two of the bridges, the Fourth bridge and al-Hurriya, also known as the al-Jamhuriya. They will either have to repair them or install floating bridges to reconnect east and west Mosul. Stratfor images showed how the bridges were damaged.

Humanitarian crisis Iraqi military engineers installed a floating bridge across the Tigris river in May, after recapturing eastern Mosul, reconnecting the two halves of the city to facilitate troop deployments ahead of the final assault to dislodge IS.
The Iraqi authorities say 419,000 civilians have been displaced from western Mosul since February alone. However, the UN estimates rebuilding the city's basic infrastructure will cost more than $1bn.
More than 320,000 people are now living in camps or other emergency sites around Mosul. Reinstating water, sewage and electricity services, as well as reopening schools and hospitals, would cost more than twice initial estimates, the organisation said.
The UN says many of those who have fled Mosul and ended up in the camps have witnessed the deaths of relatives, friends and neighbours. How have people been affected?
More than 800,000 people have currently fled their homes as a result of fighting in Mosul, according to the International Organisation for Migration.
Most have taken refuge in nearby camps and reception centres. Others have gone to stay with relatives and friends.
Following the recapture of eastern Mosul in January, there was deep concern for thousands of people remaining in the west of the city, with food supplies reported to be very low and clean drinking water in short supply.
The UN said in late January that almost half of all the casualties in Mosul were civilians. At least 2,463 have been killed and 1,661 injured across Nineveh province since October.
UN human rights officials said in June that they had received credible reports of hundreds of civilians being shot dead by IS militants as they attempted to flee the fighting in western Mosul. Dozens more have reportedly died in Iraqi and US-led coalition air strikes.
The UN says many of those who have fled Mosul have witnessed the deaths of relatives, friends and neighbours and are suffering from psychological trauma.
