* Soldiers celebrate without waiting for victory announcement
* Iraqi forces chase last IS fighters in riverside redoubt
* IS still controls adjoining parts of Iraq and Syria
* Nearly half Mosul's residents displaced from ravaged city

Iraqi security forces expect to take full control of Mosul within hours as Islamic State's defensive lines crumble in its former de facto capital in Iraq, military commanders said on Saturday.
Dozens of soldiers celebrated amid the rubble on the banks of the Tigris river without waiting for a formal victory declaration, some dancing to music blaring out from a truck and firing machineguns into the air, a Reuters correspondent said.
The mood was less festive, however, among some of the nearly one million Mosul residents displaced by months of combat, many of whom are living in camps outside the city with little respite from the blazing summer heat.
"If there is no rebuilding and people don't return to their homes and regain their belongings, what is the meaning of liberation?" Mohammed Haji Ahmed, 43, a clothing trader, told Reuters in the Hassan Sham camp to the east of Mosul.
"We are seeing now the last metres (yards) and then final victory will be announced," a television presenter said, citing the channel's correspondents embedded with security forces fighting in Islamic State's (IS) redoubt in the Old City of Mosul, by the Tigris. "It's a matter of hours," she said.
A US-led international coalition is providing air and ground support to the eight-month campaign to wrest back Mosul, by far the largest city seized by Islamic State in 2014.
Almost exactly three years ago, the ultra-hardline group's leader Abu Bakr al-Baghdadi declared from Mosul a "caliphate" over adjoining parts of Iraq and Syria.

Artillery explosions, gunfire


A military spokesman cited by the TV said the insurgents' defence lines were collapsing. Iraqi commanders say the militants were fighting for every metre with snipers, grenades and suicide bombers, forcing security forces to fight house-to-house in the densely populated maze of narrow alleyways.
Dozens of insurgents were killed on Saturday and others tried to escape by swimming across Tigris, state TV said.
"The battle has reached the phase of chasing the insurgents in remaining blocks," the Iraqi military media office said in a statement. "Some members of Daesh have surrendered," it added, using an Arab acronym of Islamic State.
Artillery explosions and gunfire could still be heard during Saturday afternoon and a column of smoke billowed over the Old City riverside, the Reuters correspondent said.
The road where the soldiers celebrated was scarred with gaping holes from explosions and rubble from a flattened multi-storey shopping mall. Rubbish and ammunition boxes were strewn around and there was no sign of civilians.
Months of urban warfare has displaced 900,000 people, about half the city's pre-war population, and killed thousands, according to aid organisations.
Prime Minister Haider al-Abadi declared the end of Islamic State's "state of falsehood" a week ago, after security forces took Mosul's mediaeval Grand al-Nuri mosque - although only after retreating militants blew it up.
Stripped of Mosul, Islamic State's dominion in Iraq will be reduced to mainly rural, desert areas west and south of the city where tens of thousands of people live. The militants are expected to keep up attacks on selected targets across Iraq.
The United Nations predicts it will cost more than $1 billion to repair basic infrastructure in Mosul. In some of the worst affected areas, almost no buildings appear to have escaped damage and Mosul's dense construction means the extent of the devastation might be underestimated, UN officials said.
The fall of Mosul also exposes ethnic and sectarian fractures between Arabs and Kurds over disputed territories or between Sunnis and the Shia majority that have plagued Iraq for more than a decade..
