Arabat Spit
Arabat Spit or Arbatskaya Strelka, belongs partially to Kherson Oblast.
The Guardian falsely writes: "The area, Arbatskaya Strelka, is a long section of land running parallel to Crimea. Since independence it has been in Kherson province, but the land was originally part of Soviet Crimea and Vladimir Putin may be attempting to restore this Communist-era border."
