The North African branch of Al Qaeda claimed in a Web site posting Tuesday responsibility for bombings in the Algerian capital, saying suicide bombers carried out the attacks that killed at least 26 people.

A statement posted on a militant Internet Web site said two "martyrs" of Al Qaeda in Islamic North Africa drove cars loaded with 800 kilograms of explosives each "to attack the headquarters of the international infidels' den" and the headquarters of the Algerian constitutional council.

"This is another successful conquest ... carried out by the Knights of the Faith with their blood in defense of the wounded nation of Islam," said the statement.
