In short, UNRWA spokesman Sami Mshasha is interviewed in a Jordanian paper discussing the UN's plans to teach school children the historical reality of the Holocaust - the paper itself responds to the spokesman's claims regarding the Holocaust by quoting Holocaust deniers, etc.
Hamas also responds to the interview in the Jordanian paper and re-issues their past stance on teaching the Holocaust:
The [Hamas] movement asked UNRWA to stop teaching the course immediately, having already been rejected by our people with marches and sit-ins condemning [such curricula], and demand that UNRWA abides by the demands and directions of the Palestinian people, and not force us to take draconian steps that will not please Washington.
The group said, "...teaching materials contrary to the understanding and culture of the Palestinian people brings up several questions about the role played by the Agency in the Palestinian territories."
And Hamas called on the Palestinian people to be alert to this conspiracy and should show high readiness of escalating steps to take against the agency if they do not respond to our demands.
We'll see what UNRWA will do and how Hamas will react if they go ahead and actually teach the Holocaust.
