ANKARA — Turkey has said that its troops will remain in Iraq despite Baghdad’s growing anger ahead of a planned operation to retake the Iraqi city of Mosul from Islamic State group jihadists.

Baghdad has accused Ankara of risking a regional war by keeping its forces inside Iraq and called for an emergency session of the UN Security Council to discuss the dispute, which has complicated plans for the ambitious American-backed Mosul operation.

"No matter what the Iraqi government in Baghdad says, a Turkish presence will remain there to fight against Daesh (IS), and to avoid any forceful change of the demographic composition in the region," Prime Minister Binali Yildirim said in televised comments.

Turkey has an estimated 2,000 troops in Iraq -- around 500 of them in the Bashiqa camp in northern Iraq training Iraqi fighters who hope to participate in the battle to recapture Mosul, according to Turkish media.

The Turkish parliament on Saturday extended a government mandate by one year, allowing its troops to remain on both Iraqi and Syrian soil.

The Iraqi parliament labelled the Turkish troops an "occupying force", while Iraqi Prime Minister Haider al-Abadi raised fears that Turkey’s move could lead to "regional war".

Iraq has also requested an "emergency session" of the Security Council "to discuss the Turkish encroachment into Iraqi territory and intervention in its internal affairs," the foreign ministry announced.

Ankara has meanwhile summoned the Iraqi ambassador and Baghdad was summoning the Turkish envoy in a tit-for-tat move.

Yildirim on Thursday said Baghdad’s reaction was not in "good faith".

"It’s not the (Iraqi) government’s right to speak like that," he said. "When troops from 63 countries are present there, it is unreasonable (for the Iraqi government) to focus on Turkey’s presence."

Turkish Foreign Minister Mevlut Cavusoglu said Turkey was in Iraq to help work towards Baghdad’s stability and security.

"Certainly we do not want to get into a vicious circle (of words) with Iraq but God-willing, the Iraqi government will come to this understanding shortly", he told a press conference in Ankara on Thursday.

Turkish forces deployed in territory currently controlled by forces from Iraq’s autonomous Kurdish region, whose government has close relations with Ankara.

The rising tension between Ankara and Baghdad could threaten the planned major US-backed operation by the Iraqi army to retake Mosul which was captured by IS in 2014.

President Recep Tayyip Erdogan has expressed Ankara’s willingness to join the battle but Turkey also fears the operation could ignite sectarian tensions.

It is particularly alarmed by the proposed role of Iraqi Shia militia in the planned offensive as well as the use of a Kurdish militia that Ankara deems to have links to the outlawed Kurdistan Workers’ Party (PKK).

Retaking Mosul would be the most ambitious move yet for the US-led coalition against IS.

Iraq’s second city had a population of two million before being taken by IS, and the UN has said that up to one million may remain. — AFP
