The first batch of U.S.-built F-16 fighter jets are already being transferred to Ukraine from Denmark and the Netherlands and will be flying over Ukrainian skies this summer, U.S. Secretary of State Antony Blinken said on Wednesday, Paralel.Az reports citing Reuters.

Blinken, speaking at an event on the sidelines of the NATO summit in Washington, said a robust package for Ukraine will be unveiled over the next couple of days that will build a clear and strong bridge for Ukraine's NATO membership.
