Four separate courts in Turkey sentenced 12 people to jail on Wednesday for being members of the Fetullah Terrorist Organization (FETO), the group behind the defeated July 15, 2016 coup, according to judicial sources. Assad has defeated rebels in many parts of western Syria with critical help from Russian Federation and Iran.
The de-escalation zones were set up last September in an effort to scale back the conflict.
The Turkish FM also said Russian Federation and Iran, as guarantors for peaceful settlement, should fulfill their commitments and "stop Assad regime" which, according to the Turkish side, violates the security regime in Syria's Idlib.More news: French league suspends goalline technology after cup errors
Earlier Russia's Ambassador to Ankara Alexei Yerkhov and Iranian Ambassador Mohammad Ebrahim Taherian Fard were summoned to the ministry for the same reason.
Russia's relations with Turkey have suffered a blow due to the latest developments in Syria.
Ankara says YPG fighters are linked to Kurdistan Workers' Party (PKK) separatists inside Turkey, who have waged an armed campaign since 1984 that has killed more than 40,000 people.More news: Prime Minister Narendra Modi ranks third in global leaders survey
The YPG is the armed wing of the Democratic Union Party (PYD), the leading Kurdish party in northern Syria, where the majority of the country's Kurdish population was concentrated. In 2017, to prevent Turkish-backed forces from overtaking Manbij, the United States deployed its Special Forces in town, while a small Russian Special Operations team appeared in Afrin, apparently for the same reason-to keep the Turks at bay. In the attack, the rebels apparently struck an officially undisclosed number of aircraft sitting on the tarmac, killing two helicopter pilots and wounding several more service personnel. The Russian General Staff has reportedly sent a note to the Turkish military command alleging the drone attack originated from territory in Idlib province controlled by the "moderate Syrian opposition". "They will pay the price for it, if need be", reported Anadolu.
Meanwhile, Syrian government forces, backed by warplanes and attack helicopters, are closing in on the strategic Abu al-Duhur air base in the eastern Idlib countryside. "Careful operations should be carried out with intelligence from the ground or with technology". Turkey entered the war in Syria on the U.S.'s side, but has grown increasingly distant over US support for Kurdish militants.More news: Taoiseach concerned that abortion proposals 'go too far'
