The Ukrainian Embassy to the United States reprimanded the CNN broadcaster on Wednesday for materials that mark the Crimean city of Simferopol as part of Russia.
The materials in question concern the New Year's celebrations around the world, with one of them containing a photo captioned "Fireworks go off over central Simferopol, Russia."
"We hope that our friends from @CNN will do better fact checking and content choice.
Simferopol is a Ukrainian city in Crimean peninsula occupied by Russia. Don't follow Russia's playbook," the embassy tweeted, UrduPoint reported.
Crimea rejoined Russia in 2014, days after power change in Ukraine, when 97 percent of those participating in a regional referendum voted for the reunification. Russian President Vladimir Putin has said that the issue of Crimea's territorial belonging is "historically closed" as Crimean residents decided to rejoin Russia in accordance with democratic procedures.
