In the latest of a series of terror bombings, two suicide car bomb attacks on Wednesday killed at least 11 persons in the city of Bouira, dpa reported.
Another as yet unconfirmed report citing security sources said the number of victims may have been 12, for a total of 14 deaths when including the two suicide attackers.
In one attack, a suicide bomber drove his car into a military administration office in Bouira, 120 kilometres east of Algiers.
In the second bombing, a suicide attacker drove his car towards a hotel, but at the last moment diverted it to smash into a bus before exploding.
Combined, the two attacks killed 11 and wounded at least 31 persons, among them 27 civilians and four military personnel.
Reports citing security sources said that those killed near the hotel were Algerian construction workers employed by the Canadian company SNS Lavalin.
The attack comes a day after 43 people were killed and 45 wounded in a suicide car bombing in Issers, 60 kilometres east of Algiers.
The attacker drove a bomb-laden car into the main entrance of the school where police academy candidates were gathered.
The latest series of terror bombings began on Sunday when 12 people, including 11 soldiers and one civilian - were killed when suspected Islamist terrorists attacked a military convoy near the coastal town of Skikda, 350 kilometres east of Algiers.
In a reaction to the latest attacks, the Algerian government said it would "fight with firm determination for the elimination of terrorism," but at the same time Algiers would "not deviate from the path of national reconciliation."
In Brussels, the European Union condemned the new terror attacks and reiterated its support for Algerian authorities in their battle against terrorism.
