Tunisia's prime minister has fired five leading security officials after three gunmen attacked a Tunis museum, killing 21 people.
The ousted officials include the director of Tunisia's tourist police and the police chief for the neighbourhood around the Bardo Museum, government spokesman Mufdi Mseddi told The Associated Press.
Monday's decision was made after Prime Minister Habib Essid visited the neighbourhood of the attack and noted security problems, the spokesman said.
"He visited (the area around the museum) last night and saw several deficiencies. So he has decided to fire a number of officials including the Tunis police chief and the police chief for the Bardo" area that includes the museum, Mssedi said.
Tunisia's President Beji Caid Essebsi has acknowledged security failures at the museum contributed to the massacre of foreign tourists, adding that security forces are hunting for a third suspect.
"Definitely there were three," Essebsi told France media iTele television and Europe 1 radio.
"Two were killed, but there is one who is now on the run.
"In any case, he will not get very far."
Last Wednesday's attack on the Tunis museum killed 20 foreign tourists and a policeman.
Australian-Colombian dual national Javier Cameloan and his mother were among the dead.
It was the first assault claimed by the Islamic State group in the North African country and came as Tunisia - the birthplace of the Arab Spring and which held its first free elections last year - struggles with rising Islamist extremism.
On Saturday, authorities released CCTV footage showing two black-clad gunmen with automatic weapons walking unimpeded though a large lobby in the Bardo, just after noon.
The grainy footage shows the gunmen passing an unidentified male. They point an automatic weapon at him briefly before letting him leave as they make their way up a staircase.
