The last stage of Russia’s deliveries of S-400 air defence systems to Turkey is expected to be completed in November-December, Turkish President Recep Tayyip Erdogan has announced.

"We have purchased the S-400s … Deliveries are already being carried out. The last stage will be in December, or maybe even in November. We are no longer in a hopeless situation. Everything we need, we’ll buy wherever we want," Erdogan told journalists on Tuesday, as broadcast on Turkish national television.

Russia started S-400 deliveries to Turkey in July, with the second stage of the deliveries having been completed in September.
