An internet posting on Monday, attributed to a senior al-Qaeda leader in Iraq, warned that last weekend's deadly bombings in Stockholm were "only the beginning", and threatened attacks against Nato and Europe.
In an audio recording on the Shumukh al-Islam Islamic website, a man identified as Abu Suleiman al-Nasser, a leader of the al-Qaeda affiliate in Iraq, warned that the Sweden attacks were "only the beginning of a new era in our jihad", or holy war.
Suleiman, who is "war minister" of the Islamic State of Iraq (ISI), warned Nato countries to "withdraw their troops from Afghanistan immediately and unconditionally", and to "stop their war against Islam".
Otherwise, "you'll have no security" and "expect that we will strike at the heart of Europe", the speaker warned in the nearly two-minute recording.
In a separate communiqué signed in his name, the previously unheard of Partisans of Islamic Jihad urged jihadists to try to wreak havoc during the Christmas and New Year holidays in the West with false reports of imminent attacks.
