U.S. says S-400 issue is unresolved with Turkey

U.S. President Joe Biden and Turkish President Tayyip Erdogan agreed in a meeting this week that Turkey would take a lead role in securing Kabul airport as the United States withdraws troops from Afghanistan, U.S. National Security Advisor Jake Sullivan said on Thursday.
However, the two leaders were not able to resolve the long-standing issue of Turkey's purchase of Russian S-400 defense systems, Sullivan said, a bitter dispute that strained ties between the NATO allies. He added that dialogue on the issue would continue, Reuters reported.
Sullivan told reporters that Biden and Erdogan, in their meeting on Monday at the NATO summit, discussed the Afghanistan issue. Erdogan sought certain forms of U.S. support to secure the airport and Biden committed to providing that support, Sullivan said.
