Mikheil Saakashvili, a Ukrainian opposition leader and a former president of Georgia, says he has been kidnapped in Kiev and sent to Poland. Security footage showed Saakashvili being dragged from a restaurant by men in military uniforms.

It later emerged this was a government operation to deport him.

Saakashvili was a marked man in Ukraine for rallying against President Petro Poroshenko.
