Well, looks like an al-Qaeda group calling itself Brigades of the Martyr Abdullah Azzam has claimed responsibility for the Sinai bombings:
The Brigades of the Martyr Abdullah Azzam give our Arab and Islamic nation the good news of the heroic martyrdom operations in Egypt, through which our sons in the squad of the leader martyr cleansed the land of Taba from the filth of the Jews
Also claiming responsibility was the World Islamist Group who carried out the attack to avenge Palestinian and Arab martyrs dying in Palestine and Iraq.
The Jerusalem Post reports that some Palestinians believe that Israel was behind the bombings:
I think the Israeli government is behind the attacks in Taba in order to drive a wedge between the Palestinians and Egypt and show the world that we are terrorists … Sharon is the only one who benefits from such attacks, which provide him with an excuse to escalate his aggression on our people.
This opinion seems to be supported by The Muslim Brotherhood in Egypt who reportedly stated that the
… main beneficiary of these events is the criminal (Israeli Prime Minister Ariel) Sharon and his gang that supports him in the American administration.
The objective of this bombing was really to
… shift attention away from the ugly massacre carried out by the Zionist forces in the past 10 days, in which more than 100 Palestinian women, children and elderly [were killed].
So let me get this straight, the attack was both a justified response to Israeli aggression AND part of an evil plot by Sharon to distract people from said Israeli aggression.
Man… these guys have got ALL the angles covered. It’s a wonder the Muslim empire ever fell …
