Turkey is still prepared to protect Kabul airport under Taliban rule following the withdrawal of US troops, President Recep Tayyip Erdogan has said.

Turkey had offered to control and run the airport, which is key to allowing countries to retain a diplomatic presence in Afghanistan.

But the swift Taliban takeover has cast doubt on the plan, which was negotiated with US defence officials.

In a TV address on Wednesday, Erdogan said Turkey still maintained the intention to operate the airport.

"With the Taliban maintaining control over the country, a new picture appeared before us," he said.

"Now we are making our plans according to these new realities."

Erdogan said he was ready to hold talks with Taliban leaders.

"We are open to any co-operation. They [Taliban leaders] have been very sensitive towards relations with Turkey," Erdogan said.
