"Russia and other terrorist organizations — first and foremost, the Islamic State in Syria — are responsible for numerous crimes against humanity," Davutoglu said in an official statement.
"If Russia continues behaving like a terrorist organization and forcing civilians to flee, we will deliver an extremely decisive response," he added.
Russia's Foreign Ministry responded to the groundless and ludicrous accusations.
"Statements by Turkish officials that Russia secretly supports IS [Daesh] are completely unacceptable. Mr. Davutoglu, are you actually making such jokes? If this is a joke, then everyone, especially Turkey, should pay less attention to irony and more to specific actions to combat terrorism," Foreign Ministry spokesperson Maria Zakharova said during a Moscow briefing on Thursday.
Following Wednesday's deadly car bombing in Ankara, the Turkish Prime Minister claimed that Ankara will hold Moscow responsible for terror attacks in Turkey amid the Syrian war.
Ankara's enmity against Russia and Kurds is deeply rooted in its neo-Ottoman ambitions in the region and the necessity to justify Turkey's meddling into Syrian affairs.
Although the Turkish government insists that it were Kurds behind the deadly attack, experts assume that Ankara wants to use the Kurdish card in order to crack down further on the ethnic minority and justify the Erdogan government's Syrian adventure.

"The Turkish government is now charging YPG with responsibility for the blast in Ankara. It is an unbelievable scenario for many reasons. First, YPG has never looked for increased enmity on Turkey, they are just trying to equal the relations on both sides of the border. Secondly, the Turkish government is looking for an excuse to send troops to Northern Syria," Ertugrul Kurkcu, the honorary president of the Turkish Peoples' Democratic Party told Sputnik on Thursday.
"Since the beginning of the war, Turkey has been attacking Kurds both inside and outside Turkey. In Diyarbakir region, Turkish tanks, along with more than 2,000 police and soldiers, appear bent on burying in rubble the Kurds as well as PKK [Kurdistan Workers' Party] fighters," political analyst Salman Rafi Sheikh writes in his article for New Eastern Outlook.
On the other hand, Turkey is shelling parts of northern Syria to prevent the Kurdish YPG forces, fighting Daesh and al-Nusra Front, from seizing key areas along the Syrian-Turkish border.
According to Sheikh, Ankara has adopted a controversial "two-edged 'final solution,' which involves a military operation against KPP and YPG and the economic strangulation of Kurds within Turkey."
"Erdogan's ruling party, which self-ironically once called for an end to Kurdish persecution, has now been selling the 'final solution' of the Kurdish question to its voters since its initial failure to win an absolute majority in the June 2015 elections. To secure the required majority, it started conflict with the PKK, selling the idea of re-establishing the glory of the 'Ottoman Empire' under the re-defined banner of Turkish nationalism and now feels politically obliged to eradicate the Kurds," the political analyst explains.
It looks especially worrisome since Turkey's Kurdish population amounts to at least 15 million people. The Erdogan government risks alienating the country's Kurds and provoking dangerous ethnic tensions.
"In this context, Turkish Prime Minister's accusations against Russia's legitimate intervention in Syria are only a way to downplay the extent of Turkey's own hysteric drive against Kurds," Sheikh underscores.
Meanwhile, "the mainstream Western media continues to pay only lip service to the humanitarian crisis Turkey has created," he stresses.
