UK warns more to do to combat IS after Mosul victory

London (AFP) - Britain's Defence Minister Michael Fallon praised Iraq on Sunday for defeating the Islamic State group in Mosul but warned that more has to be done to combat the jihadists.

Earlier on Sunday Iraq announced victory against IS in the northern city, the country's second largest, from where the group declared a self-styled caliphate three years ago.

Battles have raged for months, leaving thousands dead and wounded, while nearly a million people have fled.

"I congratulate Prime Minister (Haider) Abadi, and the Iraqi forces who have been fighting on the ground with great bravery and care against a brutal opponent," Fallon said in a statement.

"Daesh has total disregard for innocent civilian life and we should welcome their defeat in a city that was ground zero for their so-called caliphate," he added, using an Arabic acronym for IS.

As part of Britain's involvement in the US-led coalition against the jihadist group, Fallon said British forces had struck 750 targets in the battle for Mosul.

But "there is still more to do" around the city and in the broader region, Fallon said.

"This barbaric group remains dug in west of the Euphrates and clearing operations in and around Mosul will be needed because of the threat from improvised explosive devices," he added.

As the Iraqi prime minister visited troops in Mosul on Sunday, gunfire and explosions were still audible.

IS holds territory elsewhere in Iraq and in Syria, where the US-backed Syrian Democratic Forces (SDF) are battling to oust the jihadist group from its stronghold Raqa.

The coalition against IS launched military operations in the two countries in mid-2014, while Iraqi forces launched their campaign to recapture Mosul in October.
