MOSUL, Iraq, July 9 (Reuters) - Iraqi Prime Minister Haider al-Abadi arrived in Mosul on Sunday and congratulated the armed forces for their victory over Islamic State after nearly nine months of urban warfare, bringing an end to jihadist rule in the city.

Islamic States defeat in Mosul three years after taking the city is a major blow for the hardline Sunni Islamist group, which is also losing ground in its operational base in the Syrian city of Raqqa from where it has planned global attacks.

The group, however, still controls territory in Iraq and is expected to revert to more conventional insurgent tactics such as bombings as its self-proclaimed caliphate falls apart.

The battle for Mosul - by far the largest city to fall under the militants control - has left large areas in ruins, killed thousands of civilians and displaced nearly 1 million people.

The commander in chief of the armed forces (Prime Minister) Haider al-Abadi arrived in the liberated city of Mosul and congratulated the heroic fighters and Iraqi people for the great victory, his office said in a statement.

State television later showed Abadi touring Mosul on foot alongside residents of Iraqs second-largest city.
