Algerian troops killed four armed Islamists and recovered weapons and ammunition during an operation not far from the capital on Thursday, the defence ministry said.
The four were shot in Oued Ouakser, some 40 kilometres (25 miles) west of Algiers, a statement said.
Among the materiel seized were two rifles, a pistol, along with a significant amount of ammunition, as well as explosives, radios, mobile telephones and a pair of handcuffs.
Violence involving Islamists in Algeria has fallen considerably since the civil war of the 1990s, but groups linked to Al-Qaeda in the Islamic Maghreb still carry out some attacks, mostly on security forces.
The army says more than 100 armed Islamists were killed in 2014
