US President Donald Trump will visit Turkey later this year, a Turkish official has confirmed to Middle East Eye.
Details of the visit were agreed in a call on Tuesday between Ibrahim Kalin, a senior aide to Turkish President Recep Tayyip Erdogan, and US National Security Advisor John Bolton.
The official told MEE that the visit would take place in July although final dates are still to be agreed.
Both countries are members of the NATO military alliance but relations between Ankara and Washington have been strained on a number of issues, including Turkey's proposed purchase of S-400 missiles from Russia and US support for Kurdish forces during the battle against the Islamic State group in Syria.
Trump and Erdogan spoke to each other in a telephone call on Monday to discuss the S-400 deal, which the US has warned could allow Moscow to obtain critical data about its F-35 fighter jet programme in which Turkey is also a partner.
Bolton and senior US soldiers visited Turkey in January to discuss Trump's proposed withdrawal of US troops from northern Syria, although officials told MEE that Bolton's delegation had not presented any specific details about US plans.
