Turkish President Recep Tayyip Erdogan threatened again today that his country will not ratify the request of Sweden and Finland to join NATO until the promises made by those two countries to Turkey are fulfilled.

-Until the promises made to us are fulfilled, we will maintain our principled position, Erdogan said in his address to the Turkish Parliament.

Since May, Turkey has been threatening to block the entry of the two Scandinavian countries into NATO.

In June, she withdrew her objection to Sweden and Finland joining the alliance, but warned she would block the process if they failed to extradite suspects linked to outlawed Kurdish groups or the network of exiled cleric Fethullah Shulen, who is accused in the country of organizing of the failed coup of 2016.

The admission of the Nordic countries must be approved by the parliaments of all 30 NATO member states, and the Turkish Parliament could refuse to ratify the agreement.

Turkey accuses both countries of being too lenient towards groups it considers threats to its national security.
