Tunisian authorities say they have killed one of the militants linked to the attack on a museum earlier this month in which 21 tourists died.
Lokman Abu Sakhra was one of nine armed militants killed in a raid on Saturday, the government says.
A spokesman described him as one of Tunisia’s “most dangerous terrorists”.
On Sunday, French President Francois Hollande and other foreign dignitaries will join thousands of Tunisians marching in protest against terrorism.
At least 21 foreigners were among those killed when gunmen stormed the museum in Tunis on 18 March. British, Japanese, French, Italian and Colombian tourists were among the dead.
A spokesman for the Tunisian prime minister told the BBC that Sakhra, an Algerian citizen, was killed by security forces in the western region of Gafsa.
Security officials allege that the militants were members of the Okba Ibn Nafaa Brigade, a jihadist group that has previously claimed deadly attacks against security forces in the country.
In the past week, authorities claim to have arrested dozens of people they suspected of links to the museum attack.
