Russian President Vladimir Putin called Turkey’s downing of Su-24 jet a “stab in the back,” which caused the phrase to trend on Twitter in Russia.

Russian users have begun tagging their posts with #УдарВСпину (“stab in the back”) as they encourage people to boycott Turkey and accuse the government of President Recep Tayyip Erdogan of working with the Islamic State (ISIS/ISIL) in Syria.

Translation: Boycott Turkey! No Tourism!

Translation: NATO is in ISIS’s service.

Translation: History repeats itself. After 100 years, Turkey once again betrays its allies.

Russians enjoy vacations in Turkey, but now some will rid themselves of any reminders of the NATO country.

Translation: Magnets from Turkey are now in the trash can.

Translation: This creature dared to attack our aircraft! Turkey must answer!

Russians also accused Turkey of supporting ISIS.

Translation: Supporters of terrorists.

Translation: Turkey funds and sponsors global terrorism and ISIS.

Translation: Turkey = Terrorism
