Nineteen people, including 17 foreign tourists, have been killed after gunmen targeted the Bardo Museum in central Tunis, in the Tunisian capital, the Prime Minister, Habib Essid has said.
Italian, Spanish, Polish and German citizens were among those killed, as well as a Tunisian and a police officer, PM said.
Media reports suggest the death toll could be as high as 22.
Security forces killed two gunmen and were searching for accomplices, the prime minister said.
At the time of the attack deputies in the neighbouring parliamentary building were discussing anti-terrorism legislation. Parliament was evacuated following the attack.
Mr Essid said: “We have not established the identity of the two terrorists… Reports are not final, these two terrorists could have been assisted by two or three other operatives.”
Security operations were “still underway”, with forces “continuing to comb the area to find out the remaining operatives, if any”, he said.
