Security officials in Tunisia say a police officer has been killed and another wounded in a knife attack in the coastal resort of Sousse.
Three assailants were shot dead after the incident, which is being described as a terrorist attack.
Sousse was the scene of one of Tunisia’s worst attacks, when 38 people, most of them British tourists, were killed by a gunman.
The latest incident comes two days after a new government was sworn in.
“A patrol of two National Guard officers was attacked with a knife in the centre of Sousse,” National Guard spokesman Houcem Eddine Jebabli said, according to the AFP news agency.
“One died as a martyr and the other was wounded and is hospitalised,” he said.
“This was a terrorist attack”.
The knifemen stole guns and a police vehicle during the attack before making off, Mr Jebabli said. Security forces took off after them through the tourist areas of El Kantaoui.
“In a firefight three terrorists were killed,” he said, adding that two guns and the car were recovered.
Thirty-eight people lost their lives when a gunman opened fire on tourists staying in El Kantaoui in June 2015. Thirty of those killed were British tourists staying at the Hotel Rui Imperial Marhaba.
The Islamic State (IS) said it was behind the attack by Tunisian student Seifeddine Rezgui.
The situation in Tunisia has improved greatly since then, although a state of emergency is in place.
This week Tunisia’s parliament approved a new government formed by Prime Minister-designate Hichem Mechichi.
Mr Mechichi appointed technocrats to his government rather than members of political parties as had been the case in the past.
