An attacker killed a French citizen and wounded a soldier with a knife in northern Tunisia state media quoted the Interior Ministry as saying.
Interior Ministry spokesman Khaled Hayouni was quoted on state news agency TAP as saying police knew the identity of the assailant, a 28-year-old man with a criminal record, but he did not give a motive for the killing.
The attack took place in Jarzouna, a town to port city Bizerte, the day after Tunisia’s presidential election.
The attacker assaulted the uniformed soldier and then the French citizen, who died before reaching hospital, it quoted Hayouni as saying. Reuters could not immediately reach Hayouni for comment.
Jihadist militant groups repeatedly attempted to target security services and foreign tourists in Tunisia.
Two attacks in 2015 in Tunis and Sousse killed foreign tourists, but Western diplomats say Tunisian security services are now better equipped to deal with militant threats.
