On 24 November 2015, Turkish F-16 combat aircraft shot down a Russian Su-24 during an airspace dispute close to the Turkish-Syrian border. Russian President Vladimir Putin described the incident as "a stab in the back by the accomplices of terrorists" and further stated that "today's tragic events will have significant consequences including for relations between Russia and Turkey".
7 months later, on 19 July 2016 WikiLeaks released the AKP Emails. AKP is the ruling party of Turkey and political force behind president Recep Erdoğan.
