"In recent weeks, there was no warning or emergency information from foreign investigating authorities about a possible attack of "Al Qaeda" in a European country.Although its new leader Αyman Zawahiri had mentioned in early June 2011 about an attack of "Al Qaeda" in the U.S. and its allies as a revenge for the death of Osama bin Laden, there seemed to be no particular concern among the European law enforcement authorities. Moreover in Norway which is not a member of the European Union and has not participated in the main institutions of the secret and investigative services for exchanging information".This is what a senior officer of the Greek Ministry for Civil Protection told the newspaper "Vima", who monitors the issue of international terrorism a few hours after the bomb attempt against the government buildings in downtown Oslo.The Greek officer said that "it is still too early to make any conclusions about what happened in the Norwegian capital. After the first inspection, however it appears that in the attack, probably made using a car bomb, there are many similarities with the attacks in November 2003 in Turkey.At that time in Istanbul were carried out four suicidal attempts with car bombs against two synagogues, the British consulate and British bank HSBC, and the total number of the victims reached 63.Perhaps this was once again an absolute surprise of "Al Qaeda" for the secret services of the Western authorities. Now probably they will review the provisions for the safety and once again on the agenda will appear the fear of a new attack. "According to these same sources, members of 'Al Qaeda' may have sought the "weak spot" of Europe to carry out a bloody attack and apparently they found it in the Norwegian capital.It has been noted that since July 7, 2005 when there were four suicide bombings in the London Underground and in a bus where there were 53 people killed, no armed attack has been made by "Al Qaeda" on the territory of Europe. Nevertheless, on December 25, 2009, during a flight from Amsterdam to Detroit a Nigerian tried to blow up the plane with explosives hidden in his clothes.It is noted that according to the report of the European police in 2010 in Europe were carried out three attacks related to Islamist groups in two Scandinavian countries (Denmark and Sweden), and 179 people have been arrested.The sad aftermath of the shooting on the island Utoya is at least 85 people killed, while the number of victims of the bombings in the centre of Oslo reached 7 people.
