Soldiers killed the four "terrorists" during the operation in the Tizi Ouzou region, 110 kilometres east of Algiers, also seizing Kalashnikov-type weapons, a statement said yesterday.
Algerian authorities use the term "terrorists" for armed Islamists who have been active in the North African state since a devastating civil war in the 1990s.
This year, over 100 suspected Islamists have been killed in army operations in the east and south of the country, according to an AFP count compiled from official statements.
