The Secretary-General of the North Atlantic Treaty Organization (NATO) said that the S-400 missile systems that Turkey has purchased from Russia is a threat to NATO aircraft.

Iran PressEurope: NATO Secretary-General Jens Stoltenberg said on Tuesday night that the Russian-made S-400 missile system could not be integrated into NATO air defense because it was incompatible with the technologies used by NATO countries.

The NATO secretary-general said the missile system is dangerous for NATO aircraft, noting that he supported Turkey's talks over buying Patriot air defense systems instead of the Russian S-400.

Earlier, Jens Stoltenberg lamented the US sanctions imposed on Turkey over the purchase of the S-400 but stressed that he did not approve Turkey's choice too. 219
