Al Qaeda claimed responsibility for a double car bomb strike in Algiers on Tuesday that killed dozens of people as rescuers desperately worked through the night to find survivors.
Amid a disputed death toll, rescuers pulled six people alive from the debris of one of the bombs which tore through the offices of the UN High Commissioner for Refugees and other UN agencies.
The second attack killed and maimed students packed in a bus passing a car as it was detonated outside the country's highest court in central Algiers.
The government said 26 people were killed and 177 injured wounded by the two bombs. Hospital sources gave a toll of 67 dead and about 100 injured.
The United Nations said at least 10 of its staff were killed and an unspecified number were still unaccounted for.
