Tunisia has banned the wearing of the niqab in public institutions for security reasons following three terror attacks.

Prime Minister Youssef Chahed's decision to ban the full face veil follows a suicide bombing in Tunis on Wednesday by a wanted militant.

Witnesses said the suicide bomber who blew himself up was disguised in a niqab.

The country is also at the height of a tourist season in which it hopes to draw record numbers of visitors.
