Footage of an anti-Semitic rant by a knife-wielding imam to a crowd at a mosque in Rafah, Gaza, urging Muslims to stab Jews - and advising them how best to do so - went viral last week, prompting shock and revulsion.

But such "demonstrations" are commonplace throughout the Hamas-ruled territory, including during celebrations to mark the murder of three Jews and the wounding of scores more in Jerusalem and Ra'anana last week.

On Friday, a similar rally was held on the streets of Rafah, in which a large crowd of locals gathered to call for more knife attacks against Jews, many of them waving massive butchers' knives and meat-cleavers.

The footage is yet another example of the widespread hatred of Jews, fanned by Islamist groups, that is feeding the continue wave of Arab terrorism.
