RT Report All Russian military planes have safely returned to base in Syria after combat missions, the Defense Ministry said in a statement, adding all drones are operating as planned. Earlier, the Turkish military said it shot down an aircraft on the Syrian border.

“All planes of the Russian Air Group in the Syrian Arab Republic have returned to the Hmeimim Airbase after completing their combat missions. Russian unmanned aerial vehicles conducting monitoring and aerial reconnaissance on the territory of Syria, are operating in the routine mode,” Defense Ministry official spokesman Major General Igor Konashenkov told journalists on Friday.

Earlier on Friday, Turkey’s military said in a written statement that it downed an unidentified drone in Turkish airspace around 3km from the Syrian border.

The military added that it issued three warnings before shooting down the drone.

At the same time, a US official has told Reuters Washington suspects that the drone shot down by the Turkish military was Russian. The official, who spoke on condition of anonymity, declined to provide further details saying that the information was still preliminary.

Russian airplanes previously violated Turkish airspace near the Syrian border on October 3. The incident prompted Turkey to scramble two F-16 jets. On October 5, Russia admitted making a mistake explaining that bad weather caused the warplanes to violate Turkey’s airspace. Ankara has accepted the matter, saying the same day that there is no ill feeling between the two countries.

Russia’s accidental excursion into Turkey – a NATO member state – prompted the military alliance to slam Moscow for what it deemed “irresponsible behavior.”

NATO Secretary-General Jens Stoltenberg gathered a meeting of bloc member states on October 5, following which it released a statement condemning the “incursions into and violations of NATO airspace.”

In response to the criticism Russia’s envoy to NATO said on October that similar incidents have been previously “clarified through bilateral or military channels” adding that it’s “a common practice.”

NATO has ignored clarifications from Russia about the plane incident saying that all attempts to explain the reasons behind the incident fell on deaf ears, he said.

He also accused NATO of using the incident to “include NATO as an organization into the information campaign unleashed in the West, which perverts and distorts the purposes of the operation conducted by the Russian air forces in Syria.”

Khmeimim Airbase, located in Syria’s northwestern Latakia province, is the strategic center of Russia’s military operation against IS, launched on September 30.
