Tunisia's government says security forces have killed two gunmen hiding in a town near the Libyan border, where a manhunt followed an unusually violent attack earlier this month.

Three civilians and a member of the national guard were wounded by shots fired by the gunmen in Saturday's standoff outside Ben Guerdane, the Interior Ministry said in a statement.

Seven civilians, 12 security forces and 49 assailants have been killed in the area since gunmen attacked Ben Guerdane on March 7, according to the government.

The attack heightened international concerns about lawlessness in Libya, where Islamic State extremists are expanding.

Other fighting was reported Saturday near Tunisia's border with Algeria. Defense Ministry spokesman Belhassen Oueslati said one soldier was wounded in a shootout in the Kasserine region.
