Turmezistan

Turmezistan was a nation on Earth.

During the Zygon rebellion in 2015, the rebel Zygons from the splinter group Truth or Consequences had a training camp hidden in a town in Turmezistan. The Zygons had replaced everyone in the town, and imprisoned Osgood there after they captured her.

UNIT dispatched the Twelfth Doctor and a strike team to rescue Osgood and negotiate peace. However, the rebels lured the UNIT soldiers into an ambush by impersonating their family members, killing them all before escaping. The Doctor found Osgood hidden inside the town church and fled with her as UNIT bombed the town. (TV: The Zygon Invasion)

The United Nations had a base in Turmezistan. When a pyramid mysteriously appeared in a potential war zone, the Doctor was summoned. Along with Bill and Nardole, the Doctor investigated the pyramid. (TV: The Pyramid at the End of the World)
