Turkish President Recep Tayyip Erdogan has threatened with closing Incirlik airbase, which hosts US nuclear warheads. The declaration was made after US senators backed legislation to impose sanctions on Turkey due to the purchase of Russian S-400 missile defence system and its military intervention in northern Syria. Incirlik airbase is located in Adana, 150km away from the Syrian border and the US has been operating drones from there to carry out air attacks against ISIS since 2011. Erdogan also threatened to close down the Kurecik radar base, which belongs to NATO and to recognize the killing of Indigenous Americans as genocide, in response to the recent US Senate voting recognizing the mass killings of Armenians as genocide. The US lower house is trying to push President Donald Trump to take a harder stance against Ankara and apply the 2017 sanctions law that establishes financial penalties for countries doing business with Russia’s military. Turkish Foreign Minister Mevlut Cavusoglu declared that Turkey will not cancel the arms deal with Russia “whatever the consequences”.
