A long-term state of emergency in Tunisia has been extended by a further month.
It was imposed after a suicide attack on a police bus almost three years ago.
The state of emergency has been extended a number of times, most recently by one month from Monday, the Foreign and Commonwealth Office said in an updated travel advisory.
“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 FCO said.
“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, including against UK and western interests.
“Security forces remain on a high state of alert in Tunis and other places.
“You should be vigilant at all times, including around religious sites and festivals. In more remote areas of the country, including tourist sites in southern Tunisia, security forces’ response times to an incident may vary.”
