Addressing his ruling Justice and Development (AK) Party MPs at the Turkish parliament in Ankara Tuesday Turkish Prime Minister Ahmet Davutoglu said: "Neither Daesh nor YPG are primary components of these territories. The YPG and the PYD are legionnaires [and] hired soldiers of Russia".

Turkish military has been shelling PYD and PKK positions in northern Syria for three consecutive days in retaliation to artillery fire from PYD forces based around Azaz town located in Aleppo’s northern countryside Saturday night.

The exchange of fire came after YPG's recent advance into Azaz which has been the scene of recent heavy fighting just six kilometers (four miles) from the Turkish border.

About the YPG attack on Turkey he said the "latest attacks obviously targeted Turkey and threatened its border security".

"Turkey will continue to retaliate whenever and wherever it is necessary in order to protect its own borders [and] prevent an ethnic cleansing that poses threat for its security; [it will not] allow any further human tragedy or intense refugee flow and [it will] prevent the weakening of Syrian opposition forces" he added.

Davutoglu reiterated that Ankara regards the PYD and the YPG not as Kurdish groups but as terrorist organizations since they are Syrian extensions of terrorist PKK.

"PYD and YPG are puppets of Russia and subcontracted organizations used by the 'blood-spillerAssad regime' and Russia" he said.

Turkish premier noted that Moscow and Assad regime were displacing thousands of people by using the PYD in order to change the ethnic demographic nature ofSyria's north and byallowing a certain demography to exist in Aleppo that is dominated by pro-regime elements.

Turkish premier further said that the PYD was fighting Syria's moderate opposition under the pretext of battling Daesh.

"Gaining legitimacy from the international community under the pretext of carrying out an anti-Daesh fight Russia and PYD aim at empowering the Assad regime by attacking only anti-Assad groups without any single assault on Daesh" he said.

"Ethnic cleansing has been carried out on all anti-regime opposition groups not affiliated with Daesh so as to clear them out of Syria" Davutoglu added.

He added that Turkey's recent shelling and operations have halted YPG's advance in Azaz.

Davutoglu also touched upon the intensified Russian aerial offensives on northern Syria saying Russian fighter jets were randomly shelling bombs over the area without distinguishing between civilians and the military.

"Russian warplanes are not only using smart bombs but they are shelling all their bomb stocks without thinking or estimating where they hit since they are trying to use up their expired bomb stock in their inventories" he said.

The premier added that Russian jets conducted200 such sorties over the little town of Azaz on Monday alone.

Last week the YPG with Russian air cover began a massive offensive aimed at capturing opposition-held areas of the Aleppo countryside.

In recent days the group managed to seize control of several villages and a military airport in the area.

Monday saw Russian warplanes targeting two schools and a hospital in Azaz;another hospital in Idlib managed by Geneva-based Doctors Without Borders was also hit that left more than 30 people including women and children dead.

Turkish Foreign Ministry issued a statement to strongly condemn the Russian offensives calling them an "unconscionable and obvious war crime under international law".

"If the Russian Federation does not end those attacks immediately which removes peace and stability it is inevitable that Russia will face bigger and more serious results" the statement added.

UN human rights spokesman Rupert Colville also told a news conference on Tuesday: "If it was deliberate intentional targeting of those facilities it could amount to a war crime".

Syria has remained locked in a vicious civil war since early 2011 when the regime of President Bashar al-Assad cracked down on pro-democracy protests with an unexpected ferocity.

Since then more than 250000 people have been killed and more than 10 million displaced according to UN figures.
