Turkish President Recep Tayyip Erdogan has warned Russia that it will "have to endure consequences”, after a Russian plane reportedly crossed into the country’s airspace two days ago. Turkey has threatened action if the infringements continue. However, Russia has denied the claims.

On Saturday, the Turkish foreign ministry released a statement saying Russian SU-34 jet crossed into Turkish airspace at 11:46 local time the previous day, despite several warnings from air traffic authorities in Russian and English. The government has asked the Russian ambassador in Ankara to immediately condemn the incident.

“Statements by the Turkish side of an alleged case of violation by the Russian Su-34 aircraft of airspace are unsubstantiated propaganda,” Russian Maj Gen Igor Konashenkov, a ministry spokesperson. However Erdogan dismissed this and said his country views the violations as “an effort by Russia to escalate conflict in the region”.

Tensions have been rife between Turkey and Russia for several months now. In November, Turkey shot down a Russian plane that it said had entered its airspace despite warnings. The purported infringement took place near the Syria border. Russia, subsequently sent missiles to Syria and placed economic sanctions on Ankara amounting to at least $10 billion. Russia has been carrying out air strikes in Syria since September in support of its ally, Syrian President Bashar al-Assad.
