Battle for Mosul: The story so far Battle for Mosul: The story so far
(1 day later)
Iraq's prime minister has arrived in the city of Mosul to congratulate Iraqi forces on a "great victory" over the so-called Islamic State (IS). The battle for Mosul was a huge military operation to recapture Iraq's second largest city from so-called Islamic State (IS).
Haider al-Abadi arrived in "the liberated city" and praised "the heroic fighters and the Iraqi people on the achievement of the major victory," his office said. Mosul fell to IS in June 2014, with IS leader Abu Bakr al-Baghdadi declaring a "caliphate" from its ancient and now destroyed al-Nuri mosque.
Government forces had spent days closing in on the last area of western Mosul held by IS, after an eight-month offensive to drive the jihadist group from the city. Thousands of Iraqi soldiers, Kurdish fighters, Sunni Arab tribesmen and Shia militiamen, assisted by US-led coalition warplanes and military advisers, took part in the offensive, which began in October 2016.
Iraqi army forces, who cleared the eastern half of Mosul in January, had encircled fighters in a small pocket of the densely-populated Old City. Final battle
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. Iraqi Prime Minister Haider al-Abadi formally declared victory over IS in the city on 10 July.
What happened in Mosul? He waved a national flag with troops after announcing the "collapse of the terrorist state of falsehood".
Thousands of Iraqi security forces, Kurdish Peshmerga fighters, Sunni Arab tribesmen and Shia militiamen, assisted by US-led coalition warplanes and military advisers, were involved in the offensive to recapture Mosul. As he spoke, clashes were still being reported in a small part of Old City, where a few dozen IS militants were still holding out.
The operation was launched on 17 October 2016 after the rapid advance of IS militants across Iraq and Syria in 2014. IS forces were pushed back into the Old City, which is a densely built-up area interconnected by small alleyways, after being encircled by pro-Iraqi government forces in the west and east.
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. Hundreds of thousands of civilians have fled the city, much of which has sustained heavy damage during the eight-month offensive.
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. How the offensive unfolded
How much territory does IS hold? The operation was launched on 17 October 2016 with the aim of retaking Mosul and the swathe of territory in northern Iraq captured by IS militants in 2014.
According to analysis by IHS Conflict Monitor, IS fighters have lost a significant amount of territory since the regional offensive began. Progress was initially swift, with pro-government forces advancing from the north, south and east, seizing outlying towns and villages despite strong resistance.
However, their losses slowed when Iraqi government forces met stiff resistance in the city of Mosul. Iraqi special forces first entered Mosul on 1 November 2016.
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 made their last stand. But progress slowed as troops encountered fierce resistance from IS, including snipers, suicide bombers and shellfire.
The densely-packed housing and narrow alleyways enabled a relatively small number of militants to target the advancing troops with snipers and suicide bombs. By January 2017 eastern Mosul was back under Iraqi government control, who announced its full "liberation".
But the west of the city presented a more difficult challenge. The densely-packed housing and narrow alleyways enabled a relatively small number of militants to target advancing troops with snipers and suicide bombs.
How territory was regained

The jihadists constructed barricades across key routes and razed buildings so fighters could see the advancing troops. 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.
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 also revealed how the jihadists constructed multiple barricades across key routes into the city, including north of the airport.
The barriers were made out of concrete blocks and other rubble, Stratfor's analysis said, 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.
