Badush camp, set up for civilians who escaped the Tal Afar battle between Iraqi forces and the Islamic State group, stands almost empty but for a handful of displaced residents, doctors and guards.

The rows of tents erected for the displaced from the northern Iraqi city remain virtually empty.

Iraqi authorities and aid groups set up the camp, 150 kilometres (95 miles) southeast of Tal Afar, to host those displaced from the last major battle in the northern province of Nineveh.

Army, police and units of the Hashed al-Shaabi paramilitary coalition launched an offensive on August 20 to seize the city, having ousted IS from Iraq's second city Mosul in July.

On the sixth day of the operation, Iraqi forces announced Saturday the recapture of central Tal Afar and its historic Ottoman-era citadel, placing them on the verge of fully retaking one of the last IS strongholds in the country.

General Jabar Mustafa Hassun, from a committee dealing with the displaced, said civilians had been arriving at the camp -- but that was before the launch of the battle.

Tal Afar had 200,000 residents before the jihadist group seized it in July.

In the weeks prior to the offensive on Tal Afar, up to 90,000 people were still in the city 70 kilometres west of Mosul, according to Hassun.

The United Nations said this week that around 30,000 civilians were still trapped in the fighting.

Hassun said that "10 days ago, 4,000 to 6,000 civilians were arriving each day in the camps", but that number had fallen to "150 or 200 a day, sometimes just 50".

The displaced from Tal Afar apparently left in different directions, some of them arriving in Badush but then passing through and carrying on to other camps.

He estimated only around 160 families are left in Tal Afar, most of them the families of IS fighters.

During the fight for Mosul, the outflow of displaced people far exceeded predictions by aid groups, unlike in the case of Tal Afar which has seen no such mass exodus.

Issa Hassan, 72, was seated in a tent held erect by four poles, sheltering from the blistering sun.

The white-bearded man said he arrived this week from Al-Khan, a village near Tal Afar where he had taken refuge two years ago.

"I originally come from the Al-Jazeera district of Tal Afar," said Hassan, who had sent his four wives ahead of him to a camp near Mosul before selling his herd of goats and heading off.

A doctor at the camp, Omar Amer of an NGO called Dary, said he had spent the past two weeks at the camp.

"At first, we had families arriving, about 150 people each day," some of them suffering from malnutrition and others with injuries from explosions," he said.

"The number has gone down. We hear that other displaced people are on their way... We're ready, we're waiting."
