From SharkBlog comes the story 'Sowing seeds of hatred':

Textbooks widely used in New York's Islamic schools contain passages that are blatantly anti-Semitic, condemning Jews as a people, repeating old canards about the Jews wanting to kill Christ and faking their Holy Scriptures to mock God.

As you might have already guessed, there is something of a Saudi connection: one of the publishers was until recently a recipient of money from a Saudi foundation.

This is somewhat similar to the situation with those "free" Spanish-language textbooks the Mexican government provides to U.S. schools and libraries. Certainly, they don't cost the schools and libraries anything more than postage.

However, the textbooks supposedly have a different interpretation of the Mexican-American war, the rightful ownership of the U.S. Southwest, etc. etc. than the U.S. government's interpretation, making their social cost a bit high.
