Military aircraft will be used in the capital Ankara on Monday and Tuesday during the testing of the S-400 system’s radar-detection equipment, a Turkish defense official said, asking not to be identified in line with his department’s restrictions.
The decision comes after President Recep Tayyip Erdogan said that he told President Donald Trump during a meeting this month that Turkey wouldn’t give up on deployment of the systems, risking penalties championed in Congress.

The lira reversed earlier gains after the report, was trading 0.4% lower at 5.7365 per dollar at 11:41 a.m. in Istanbul.
