During a public speech in the capital Ankara, Turkish President Recep Tayyip Erdogan reiterated that the deal to buy S-400 missile systems from Russia has been closed. This reported by TASS.

"I’m not saying that Turkey is buying S-400 systems. I’m saying that Turkey has already bought them, and this is a done deal. They will be delivered next month," the Turkish leader said in a speech, aired by Turkey’s NTV channel.

"We are not going to request anyone’s approval to satisfy our needs regarding the defense industry. Have we not requested the United States to sell defense systems to US? We did, but they said ‘no.’ We were told that the US Congress would never let this happen," he continued.

Meanwhile, Sergei Chemezov, who heads Russia’s state corporation Rostec, said he expected the supplies to begin in two months.
