CAIRO Aug 6 (Reuters) - Egypt's Muslim Brotherhood said on its website 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 Mursi.

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