ISIS stronghold Tal Afar about to fall, Iraqi military says

Iraqi forces have raised the national flagin the heart of Tal Afar, Islamic State in Iraq and Syria's (ISIS) stronghold in the country's northwest, and say they'repoised to take full control of the city after a week-long offensive.

Tal Afar is the latest objective in the U.S.-backed war on the jihadist group following the recapture in July of Mosul, where it declared its self-proclaimed caliphate over parts of Iraq and Syria in 2014.

Tal Afar was cut off from the rest of ISIS-held territory in June, and the campaign to recapture it started on Aug. 20, when up to 2,000 militants were believed to be defending it against around 50,000 attackers, according to Western military sources.

"Tal Afar city is about to fall completely into the hands of our forces, only five per cent remains" under Islamic State control, an Iraqi military spokesman told Reuters on Saturday.

Elite forces had liberated the heart of the city "and raised the national flag on top of the citadel building," a statement from the Iraqi joint operations command said.

Much of the Ottoman-era building was destroyed by the militants in 2014.

Such a quick collapse of ISISin the city, which has been a breeding ground for jihadist groups, would confirm Iraqi military reports that the militants lack command and control structures west of Mosul.

A Reuters visuals team in Tal Afar said fighting had eased on Saturday, with just occasional artillery rounds heard. There were no sign of civilians in two neighbourhoods it visited.

"God willing, the remaining part will be liberated soon," Iraqi Foreign Minister Ibrahim al-Jaafari said at a news conference with his French counterpart, Jean-Yves Le Drian, and French Defence Minister Florence Parly, in Baghdad.

Cycles of sectarian violence

A map published by the joint operations command showed all of Tal Afar under army control barring one neighbourhood on the northeast side where fighting was continuing.

The city, which had a prewar population of about 200,000, lies on the supply route between Syria and Mosul, 80 kilometresto the east.

It experienced cycles of sectarian violence between Sunnis and Shias after the U.S.-led invasion of Iraq in 2003, and has produced some of ISIS's most senior commanders.

Mosul's collapse effectively marked the end of ISIS's "caliphate,"but the group remains in control of territory on both sides of the Syrian-Iraqi border, and of Hawija, a city between Mosul and Baghdad that Iraqi officials said would be the next target.

The group is also retreating in Syria, where it is facing two offensives, one backed by the U.S. and the other by Russia and Iran.

The number of civilians believed to have remained in Tal Afar at the start of the offensive was estimated at between 10,000 and 20,000 by the U.S. military.

Tens of thousands of people are believed to have fled in the weeks before the battle started. Those remaining were threatened with death by the militants, according to aid organizations and residents who managed to leave. On Tuesday, UNrefugee agency UNHCR said residents were arriving at refugee camps starving and with wounds from sniper fire and mine explosions.

Residents who fled Tal Afar seven days ago told Reuters on Saturday they had been surviving on bread and dirty water.

"I lost 25 kilogramsin the last three months," said Hajji Abu Mohammad, who escaped last Saturday with his wife and five children.
