NATO Secretary-General Jens Stoltenberg said on Friday that the alliance would seek to evacuate more vulnerable Afghans and maintain contact with the Taliban, but that Afghanistan's new rulers would have to show themselves worthy of aid and recognition.
NATO member Turkey, which had run Kabul airport for six years, has offered to help keep it operational now that U.S. and other NATO troops have left, and Qatar has offered to help.
Stoltenberg said he had discussed the issue with Qatar's Emir Sheikh Tamim bin Hamad al-Thani and the Qatari foreign minister.
He also said many Afghans who has cooperated with international forces and could therefore be at risk from the Taliban remained in Afghanistan.
