A suicide car blast injures nine in an attack targeting police and foreign workers.
The group, which was formerly known as the Salafist Group for Preaching and Combat, posted pictures of what it said were the two suicide bombers holding assault rifles.
The statement said that 60 people had been killed in the first attack and 50 in the second.
Witnesses said that several victims of the explosion near the constitutional court in Ben Aknoun were students on a school bus.
Al Jazeera correspondent Hashem Ahelbarra said that the attacks came after a speech by Ayman al-Zawahiri, al-Qaeda’s deputy leader, earlier this year in which asked attackers to target France, Spain and Algeria.

The al-Qaeda in the Islamic Maghreb organisation has claimed responsibility for a number of bombings that have killed several people this year.
In September, a car bomb killed 37 people at a coastguard barracks in Dellys, 100km east of Algiers, two days after a suicide bomb blast targeting a convoy carrying Abdulaziz Bouteflika, Algeria’s president, killed 22 people.
The GSPC was formed in 1998 by former members of Algeria’s Armed Islamic Group (GIA), which began attacking the government in 1992 after it cancelled elections an Islamic party looked set to win.
The US condemned Tuesday’s attack on the UN buildings, with the White House saying it would support Algeria and the UN in the wake of the attacks.
