The Tunisian government has announced a ban on all flights from the United Arab Emirates.

The ban was announced by the country’s transport ministry, with no specific reason given for the ban.

2 days ago however, UAE officials prevented all Tunisian women from entering the country.

“Based on the higher travel advisory restriction issued by the United Arab Emirates government, airlines are instructed that all Tunisian female nationals will be denied entry to the UAE by API-UAE,” read an internal Emirates Airline email.

API stands for “advance passenger information”, a system that requires airlines to provide travellers’ passport details to the country of destination before departure.

 According to the official Tunis Afrique Presse, Tunisian woman of all ages were denied permission to board their flight, even if accompanied by a spouse, and regardless of whether they were going to the UAE or intending to travel on to another destination.

The ban was lifted late Friday after the Tunisian ministry of foreign affairs “hosted” UAE ambassador Salem Issa Al Zaabi, asking for explanations.

It seems Tunisia’s ban is retaliation for the UAE’s ban. More on this story as it develops.
