A state of emergency remains in effect after the November 24, 2015, bombing of a bus carrying officers of the National Guard in downtown Tunis; at least 11 people were killed and many others were injured.
National and regional curfews, which are enforced by the police, may be imposed without advance warning.
While it has occurred mostly in central and southern Tunisia, unrest may occur throughout the country.
Demonstrations, labour strikes, roadblocks and other disturbances have deteriorated into violent clashes between the police and demonstrators, resulting in considerable property damage, injuries and deaths.
There is an ongoing threat of terrorist attack and kidnapping along the border with Algeria.
