A state of emergency was originally declared in November 2015 following a suicide bomb attack on a bus.

This came after a series of deadly terror attacks, including the Sousse beach massacre.

Thirty Britons, all Tui holidaymakers, were shot dead on a beach at Port El Kantaoui in June 2015.

Another Briton, meanwhile, was killed in an attack on the Bardo Museum in Tunis three months earlier.

Prince Harry this week unveiled a memorial in Birmingham to the 31 victims.

The Foreign Office updated its travel advice to reflect the one-month extension on Thursday evening (March 7).

“A state of emergency is in effect in Tunisia, imposed after a suicide attack on a police bus on November 24, 2015,” it reads.

“It’s been extended a number of times, most recently on March 7, 2019, by one month.

“Since the terrorist attack in Sousse in June 2015, which targeted tourists, the UK government has been working closely with the Tunisian authorities to investigate the attack and the wider threat from terrorist groups.

"The Tunisian government has improved protective security in major cities and tourist resorts.

“But terrorists are still very likely to try to carry out attacks in Tunisia.”

Last June, the Foreign Office softened its stance on travel to the country.

It no longer advises against all but essential travel to the town of Jendouba, about 120 miles from capital Tunis.

It also revised down the threat level for some areas of southern Tunisia, including Medenine, Tataouine and Douz.

The move was welcomed by the Tunisian National Tourist Office, stating it was a “huge boost” to confidence in Tunisia.

Many holiday companies in the UK have since returned to Tunisia following the Sousse attack.
