UPDATE 11:38 PDT: Now Will McCants has this: "'Helpers of Global Jihad' now says its claim is not the official claim and it had nothing to do w/ operation. Says wait for official claim."
It's Motoon Rage. From the Telegraph news feed:
18.03 Will McCants now says that Ansar al-Jihad al-Alami (Helpers of Global Jihad) seem to make a claim of responsibility. They claim it is in response to the occupation of Afghanistan and insults to the Prophet Mohammed. It has come via Shmukh, an elite jihadi forum.
McCants translates part of the message:
"We have warned since the Stockholm raid of more operations & we have demanded that the countries of Europe withdraw from the land of Afghanistan and end their war on Islam and Muslims. What you see is only the beginning and there is more to come."
And here is the full message, in my hasty translation:
Praise be to Allah from his slaves, united and humiliating the people of shirk [worship of others besides Allah] and companions of kufr [unbelief]. Prayers and peace be upon our Prophet Muhammad, the Seal of the Prophets, his family and companions and descendents.
The Almighty said: "Then fight in Allah's cause - Thou art held responsible only for thyself - and rouse the believers. It may be that Allah will restrain the fury of the Unbelievers; for Allah is the strongest in might and in punishment. [Qur'an 4:84]
Here another message from the militants has reached the countries of Europe and further proof for the countries of Europe that the mujahideen will not stand idly before their war against Islam and Muslims.
Today Norway has been targeted in order to be a lesson, and a lesson to the rest of Europe. We have warned since the Stockholm raid of more operations and we have demanded that European countries of Europe withdraw their armies from the land of Afghanistan and end their war on Islam and Muslims. We repeat our warning again to the countries of Europe and tell them that the demands of the mujahideen must be carried out. What you see is only the beginning. There will be more.
There were many reasons for the targeting of Norway. The most important is their participation in the occupation of Afghanistan and the abuse of our prophet Muhammad (peace be upon him).
Praise Allah who has enabled his slaves to be united...and pray to Allah to save our brothers and our fighters everywhere.
Glory and praise to Allah. I bear witness that there is no god but you and I repent to you.
