BRUSSELS, Oct 13 – Defense Minister Oleksiy Reznikov says that understanding of what, when and how can be delivered by partners in terms of air defense to close the Ukrainian skies will come next month.

He said this on Thursday in Brussels to Ukrainian journalists, commenting on the course of meetings in the Ramstein format and with defense ministers of NATO member countries.

"The main thing is that the political decision has been made. Then there will be testing ... I am for our expectations to be justified – tomorrow the sky will not be closed ... These are expensive systems, complex, for which you need to train – so that there are no illusions that everything will change tomorrow," he explained the situation.
