A terror group, Ansar al-Jihad al-Alami, or the Helpers of the Global Jihad, issued a statement claiming responsibility for the attack, according to Will McCants, a terrorism analyst at C.N.A., a research institute that studies terrorism. The message said the attack was a response to Norwegian forces’ presence in Afghanistan and to unspecified insults to the Prophet Muhammad. “We have warned since the Stockholm raid of more operations,” the group said, according to Mr. McCants’ translation, apparently referring to a bombing in Sweden in December 2010. “What you see is only the beginning, and there is more to come.” The claim could not be confirmed.
Norway is a member of the NATO alliance and has a small fighting contingent in Afghanistan. It was one of several countries named by Ayman al-Zawahri, the leader of Al Qaeda, as potential targets for attack. In 2006, Norwegian newspapers reprinted Danish cartoons that angered Muslims by lampooning Muhammad. Norway has also historically been a frequent participant in peacekeeping missions and a host for diplomatic talks, including the 1993 Oslo Accords between Israel and the Palestinians. The Nobel Peace Prize is awarded by a committee of the Norwegian Parliament.
Muslim leaders in Norway swiftly condemned the attacks. “This is our homeland, this is my homeland; I condemn these attacks and the Islamic Council of Norway condemns these attacks, whoever is behind them,” said Mehtab Afsar, secretary general of the Islamic Council of Norway.
