The Italian Defense Minister Antonio Martino has just stated that he considers threats against Italy by the Islamic militant group Abu Hafs Al Masri Brigade to be credible.
OBL expert and former US government adviser Michael Scheur also takes them seriously (and confirms the el mundo story indirectly):
“On the tactical and strategic levels, the London attacks were quintessentially al-Qaeda operations. At the tactical level, the attacks were preceded by the usual al-Qaeda warning that an operation in Europe was near. On 29 May 2005, the AHMB’s “European General” posted a statement on the Internet that foreshadowed the events of 7 July. In part, the statement said:
“We direct a message to America and all its allies around the world that the desecration of the Holy Qur’an will not go by without a response. In fact, the retaliation will come soon in the near future, God willing.”
All this, of course, if confirmed would bring us back to the Madrid bombings, and the Van Gogh killing in the Netherlands.
