At least six people are killed in a suicide car bomb east of the Algerian capital.
The attack happened in the coastal town of Zemmouri el Bahri 45 km (28 miles) east of the Algerian capital.
Newspapers say that the ambush was part of the army's pursuit of rebels who orchestrated a suicide car bombing which wounded 25 people in Tizi Ouzou town east of Algiers on August 3.
That attack was claimed by al Qaeda's north Africa wing, the al Qaeda Organisation in the Islamic Maghreb. There was no immediate claim of responsibility for Saturday's attack.
Al Qaeda said the August 3 blast was a message to "the sons of France and the slaves of America" that it was ready to inflict more violence to defend what it called the Islamic nation.
The group has links with like-minded militants in north Africa and is the most effective armed rebel organisation in the country of 34 million, Africa's second largest country by area.
