Iraqi PM Haider al-Abadi has visited Mosul to congratulate Iraqi forces for their “victory” over IS in the city.
Mr Abadi was there to announce the city’s full “liberation”, his office said in a statement.
Iraqi forces, backed by US-led air strikes, have been battling to retake Mosul since 17 October last year.
Islamic State militants seized it in June 2014 before taking much of Iraq’s Sunni Arab heartland and proclaiming a “caliphate” straddling Iraq and Syria.
Kurdish Peshmerga fighters, Sunni Arab tribesmen and Shia militiamen have also been involved in the gruelling battle.
The Iraqi prime minister arrived to “congratulate the armed forces and the Iraqi people” on the final defeat of IS in Mosul on Sunday, the statement said.
He met commanders in the city but has not yet given a speech formally declaring triumph.
