Tunisia's president has urged Tunisians to unite to fight terrorism, two days after an attack on the Bardo museum in the capital Tunis killed 25 people, mostly foreign tourists.
"We won't win if we don't stand together," Beji Caid Essebsi said in a national address marking 59 years of Tunisia's independence from France.
Islamic State has said it was behind the attack on the museum, which is next to the country's parliament.
Nine people have since been arrested.
The presidency said four of those arrested were directly linked to the attack and five had "ties to the cell" that carried out the attack.
Many of those who died and were injured were tourists from two cruise ships which have now have arrived in Spanish ports.

It is a grim scene at Charles Nicolle hospital in central Tunis. Family members of those who died in the attack on Wednesday have been arriving at the morgue to identify and repatriate their loved ones. Some were carrying flowers and most of them were being looked after by the consular staff of their respective embassies.
The death toll has climbed to 25 now, and some victims are still being identified. At the surgical ward nearby, patients are still being treated for injuries. The French interior minister and the Tunisian president paid a visit this afternoon.
Earlier, people came to the Bardo museum to express sympathy for those who died. A group of Tunisians were holding up banners that read: "Terrorism has nothing to do with Islam or Tunisia".
President Essebsi, who won Tunisia's first free presidential election in December, called on Tunisians to unite "in the face of terrorism, like their forefathers did in the face of the colonisers".
The BBC's Aidan Lewis in Tunis says there is a strong security presence on the streets as people came into the centre of the city for an independence day concert.
