A Tunisian soldier was killed and two wounded in a landmine blast late on Sunday, the official news agency TAP reported on Monday.
"One soldier has been killed and two others slightly wounded by a landmine set by militants near the Algerian border in Kef province," TAP quoted army spokesman Bel Hassen Ouslati as saying.
Tunisian forces are on high alert after gunmen stormed the Bardo museum in Tunis last week.
The attack killed 20 foreign tourists in the worst attack in the North African country in more than a decade.
