Turkey Announces Troop Withdrawal From Northern Iraq
Turkey is pulling more troops out of northern Iraq in an effort to deescalate tensions with the Iraqi government, a day after U.S. President Barack Obama urged Ankara to withdraw its troops.
On December 19, the Turkish Foreign Ministry acknowledged a "miscommunication" with Iraq over its recent deployment of troops to the Bashiqa military base, near the IS-held city of Mosul.
The ministry did not say how many troops would be moved or where they would be moved to.
U.S. President Barack Obama urged Turkish President Recep Tayyip Erdogan in a phone call on December 18 to "deescalate tensions" with Iraq by withdrawing its forces from the region.
The deployment of hundreds of Turkish troops -- who moved from Iraq's Kurdish region to Bashiqa earlier this month -- angered the Iraqi government, which said the soldiers had not been invited and should leave.
Turkey says that the force was part of an international mission to train and equip Iraqi forces that want to retake Mosul from Islamic State militants.

There are conflicting reports of the number of casualties in the Russian attacks on Idlib, our news desk reports:
Scores of people have been reported killed in a series of air strikes believed to have been carried out by Russian planes in a rebel-held city in northwestern Syria.
The strikes on December 20 were reported to have hit a busy market, several official buildings, and apartment blocks in Idlib, the capital of the province of the same name.
There were conflicting reports on casualties.
The Syrian Observatory for Human Rights said 36 people had been killed and many more injured.
But Reuters news agency quoted rescue workers as saying they had confirmed 43 dead but that at least 30 more bodies had been retrieved that had still to be identified.
Reuters added that over 150 people were wounded with some of the serious cases sent to hospitals in Turkey.
Idlib was captured earlier this year by a coalition of Islamist insurgent groups that includes the Al-Qaeda-linked Al-Nusra Front.
Russia has not confirmed whether it carried out strikes in the area.
Separately, the Syrian Army said on December 20 that it had seized -- with the backing of Russian air power -- a rebel-held town in southern Aleppo.
The capture of Khan Touman was seen as a major gain that opened the way for advances further to the west in Idlib Province.
In September, Russia began launching air strikes against armed groups in Syria, saying Islamic State militants and other "terrorists" were targets.
But the United States and its allies claim Russia's military involvement in the Syrian conflict aims at beefing up President Bashar al-Assad.
President Vladimir Putin said on December 19 that Russia’s armed forces had not utilized their full capability in Syria and would use "more military means" there if necessary.
He made the comments a day after the United Nations Security Council unanimously adopted a resolution that endorses an international road map for a peace process in Syria, where the civil war is heading into its fifth year.
The peace plan calls for a cease-fire, talks between the Syrian government and opposition in early January, a transitional government within six months, and elections under UN supervision within 18 months.

Sky News reports this morning that it has uncovered evidence that Russia may be covering up the true number of military deaths in Syria.
Sky claims that Moscow is carrying out military funerals on the quiet and withholding information about servicemen's deaths.
Following up on information passed to us by investigative bloggers led by Ruslan Leviev, we travelled to a small village near the Belarus border called Paltso to investigate the death of a 27-year-old special-forces soldier called Fyodor Zhuravlyov.
He was buried in the village cemetery in a quiet ceremony three weeks ago and his parents said the authorities had not told them what had happened to their son.
Yet we learned that it was "common-knowledge" on our visit to the village that Zhuravlyov had died in Syria.
George Brandis, Australia’s attorney-general, has warned that the IS group is seeking to create a “distant caliphate” in Indonesia, the world’s most populous Muslim nation.
“[IS] has ambitions to elevate its presence and level of activity in Indonesia, either directly or through surrogates,” he told The Australian newspaper.
“You’ve heard the expression the ‘distant caliphate’? [IS] has a declared intention to establish caliphates beyond the Middle East, provincial caliphates in effect. It has identified Indonesia as a location of its ambitions.”
