Turkey's President Recep Tayyip Erdogan said 100 Turkish specialists were sent to Russia to undergo a training course to operate the S-400 missile defense systems.
"I hope a major part of S-400 components will be delivered by the end of this year and the entire process will be over by April 2020. And after that, we will continue to follow our path with bigger confidence," the Haberturk television channel quoted him as saying.
According to the Turkish leader, more Turkish specialists may be sent to Russia to undergo a training course to operate the missile defense systems. "Their current number is not enough. Now there are 100 specialists but this number may be increased ten-fold," the Turkish leader added.
Earlier in the day, the Turkish president said the S-400 deal with Russia was a most important agreement for present-day Turkey.
