TWO car bombs rocked a hotel and military headquarters in Algeria on Wednesday, killing 12 people, a day after a nearby suicide bombing killed 43.
The double attack was the sixth major terrorist operation in the country this month.
No group has claimed responsibility for the recent spate of killings, including the two remote-controlled car bombs that struck the city of Bouira on Wednesday.
All six occurred in the area east of Algiers where the al-Qaida Organisation in the Islamic Maghreb (AQOIM) is believed to operate.
Violence in this gas and oil-rich US ally has surged since the Groupe Salafiste pour la Predication et le Combat, which led a deadly insurgency in the 1990s, joined Osama bin Laden's terror network and took the AQOIM mantle in 2006.
Terrorism expert Jean-Louis Bruguiere suggested that the group was receiving military reinforcements from al-Qaida in Iraq.
