Mossad behind Sinai attack, says Muslim Brotherhood. What took them so long?

Don't get excited: the text follows the usual formula:

Egypt's Muslim Brotherhood said on its website on Monday that the attack on a police station in Sinai on Sunday in which 16 policemen were killed "can be attributed to Mossad" and was an attempt to thwart Islamist President Mohamed Morsi.

The statement said the Mossad was trying to abort the Egyptian uprising that toppled former President Hosni Mubarak last year and that it was "imperative to review clauses" of the agreement between Egypt and Israel.

The only question is: why was it published only on Monday, when the whole event took place on Sunday? Hm...

Oh, and the usual crowd is out in force, of course. Check this out.

Update: And yes, some Egyptians are receptive...
