Turkey tests Russian-made S-400 defence system
A Haber television, which is close to the government, said on its website that Turkey's military test-fired the Russian S-400 air defence system in the Black Sea province of Sinop. It based its reports on an amateur video, reportedly filmed in Sinop, showing a contrail shooting into the sky. Other media carried similar reports.
Turkish military and defence officials have refused to comment on the reports.
Washington strongly objected to Turkey's acquisition of the Russian anti-aircraft system and suspended Turkey from its hi-tech F-35 fighter jet program, saying the S-400 are a threat to the stealth fighter jets.
It has also warned Ankara that it risks US sanctions under the Countering America's Adversaries Through Sanctions Act if the S-400 system is activated.
Turkey insists it was forced to purchase the Russian system after Washington refused to sell it the US Patriot system.
Russia delivered the first batch of the Russian defence system last year. Turkey had initially said the S-400 would be operational in April but it has since delayed activating the system.
During a visit to Turkey earlier this month, NATO Secretary General Jens Stoltenberg reiterated that the Russian-made S-400 system cannot be integrated into the NATO air and missile defence system and can lead to sanctions by the United States.
