Last year, two major attacks on popular tourist spots killed dozens of foreigners in the country.
In March, 22 people died when the Bardo Museum in Tunis was targeted, and in June, 38 people were killed when a gunman opened fire on tourists on the beach in Sousse.
The so-called Islamic State group, which now has a foothold in Libya, claimed responsibility for those attacks.
There was criticism at the time of Tunisia’s failure to deal with the militant threat.
The instability in Libya has allowed that threat to grow and Tunisia has responded by building a trench along the border to try and stop fighters infiltrating.
