Former Georgian president Mikheil Saakashvili was banned from entering Ukraine for three years after Kiev deported the opposition leader earlier this month.
Ukrainian border service spokesman Oleg Slobodyan said that Saakashvili was banned on the orders of the commander in charge of the border section he illegally crossed in September.
Saakashvili had been living in exile in Ukraine before being detained by masked men at a Kiev restaurant and deported to Poland on February 12, AFP recalls.
A court in September found Saakashvili guilty of illegally crossing Ukraine's border after he forced his way back into the conflict-riven country with the help of hundreds of supporters, pushing aside border guards.
Ukraine stripped him of his citizenship in 2016, rendering him stateless as he had already lost his Georgian citizenship.
