Three Algerian soldiers have been seriously wounded by a bomb that hit their convoy in eastern Algeria, a security source has said.
The bomb went off on Sunday when the convoy drove through an area near the eastern town of Tebessa, 600km from the capital, Algiers, the source reported on Monday.
The attack came one day after the army said it defused three home-made bombs near a military checkpoint in the Kabylie region.
Two car bombs killed at least 37 people, including 11 UN employees, in Algiers on December 11.
The military-backed government scrapped legislative elections in 1992 as the Islamic Salvation Front (FIS), an Islamist party, was on its way to a comprehensive win.
An estimated 200,000 people have killed in fighting since then.
The violence had subsided, but in the past 12 months has regained some of its former intensity.
