President Beji Caid Essebsi said on Tuesday that the state of emergency will continue until February 21, 2016.

Tunisian authorities also imposed a curfew on Tunis and closed the border with Libya, where investigators believe the attack was planned.

Earlier attacks -- at the National Bardo Museum in Tunis and at a hotel near the Mediterranean resort of Sousse -- killed 60 people, most of them foreign tourists.
