ANKARA: Turkey said Wednesday it had started pulling troops out of Afghanistan, apparently abandoning plans to help secure Kabul's strategic airport.

Ankara had been hoping to gain a foothold in Kabul after the US troop withdrawal is completed on Tuesday.

But the Taliban's swift capture of the Afghan capital left those plans in disarray, eliminating a key point of leverage in its tumultuous relations with the United States.

"The Turkish Armed Forces are returning to our homeland with the pride of successfully fulfilling the tasks entrusted to it," the Turkish defence ministry said in a statement.

Turkey had more than 500 non-combat troops stationed in Afghanistan as part of NATO's now-abandoned mission in the war-torn country.

Turkish President Recep Tayyip Erdogan said Ankara was still interested in playing a role in Afghanistan, keeping its lines of communication open with Taliban leaders.

"It is important for Afghanistan to stabilise," Erdogan said as the troop withdrawal was announced.

"Turkey will continue to be in close dialogue with all parties in Afghanistan in line with this goal."

The Turkish defence ministry also left open the option of playing a security role in Kabul down the line.

"Turkey will continue to be with the Afghan people as long at they want," it said, noting the troops had been stationed at the airport for the past six years.

   **- 'Additional burden' -**

Erdogan has been under intense political pressure at home not to accept migrants that might come from Afghanistan.

Turkey became home to more than four million migrants -- most of them from Syria -- under a deal that helped stem the European Union's migrants crisis in 2016.

Ankara is building a wall along its eastern border to Iran to keep out Afghans trying to use the route to enter Europe.

Erdogan said Turkey was now home to roughly five million migrants of various status and could not accept any more.

"We cannot handle an additional burden of migration originating from Syria or Afghanistan," he said.

Foreign Ministry Mevlut Cavusoglu said on Tuesday that Ankara has evacuated 1,404 people from Afghanistan -- 1,061 of them Turkish nationals.

Cavusoglu added that only 200 or so Turks still wanted to get out of Kabul, leaving around 3,000 Turkish nationals who had told embassy officials that they were willing to stay.

The defence ministry said Wednesday that 1,129 people had been evacuated "with its aircraft".

It did not explain why its figures differed from those issued by Cavusoglu.
