some details to correct, Ennahdha islamist party has indeed some deep links with the AK Parti but it's not in the opposition, the current Tunisian government is a coalition between secular parties (mainly the NT party and some smaller Liberal parties) and Ennahdha, so it is actually a part of the government although to be fair, holds no big positions (defense and interior ministries are held by independent technocrats, while head of government and foreign affairs by the NT secular party)
during the last visit of Turkish president Recep Tayyip Erdoğan to Tunisia few military accords were signed, especially during a meeting between the Tunisian defense officials and their Turkish counterparts.
If I recall correctly there were 2 or 3 military agreements.
among which there was one about training troops and one about transferring Turkish military technology or something like that.
so I do hope the visit has something to do with it.
Turkish military products aren't new to Tunisia either, I believe we were the very first to buy both the Kirpi and Ejder Yalçin and other equipment from Aselsan as well.
won't be surprised if Tunisia is one of these countries:
