The British Foreign & Commonwealth Office has warned visitors to Tunisia to exercise caution ahead of government elections in the country.

The FCO warned Tunisia remains in a period of political transition following the 2011 revolution, with danger heightened during the build up to the second round of voting in the presidential election.

The first round took place on November 23rd, with a second round set to take place on December 21st.

The Tunisian authorities have announced additional security measures over the election period, including at polling stations.

“You should be vigilant on election day, and avoid political rallies and areas where large crowds may gather,” warned the FCO in a statement.

The FCO continues to advise against all travel to the Chaambi Mountain National Park area, the Tunisia-Algeria border crossing points at Ghardinaou, Nefta and El Kef, the militarized zone south of, but not including, the towns of El Borma and Dhehiba and all areas within five kilometres of the Libya border area from north of Dhehiba up to but not including the Ras Ajdir border crossing.

There have been a number of protests in the post-revolutionary period.

These are not normally aimed against foreigners, but international events can trigger anti-western demonstrations and further protests could occur.

A new exit tax of 30 dinars per person (£11) has also recently been applied to all departing, non-resident foreigners.

Some 408,655 British nationals visited Tunisia in 2013.

Most British tourists stay in the coastal resorts and most visits are trouble free.
