What was That Demonstration?

Yesterday afternoon, on my way home from Jerusalem, I noticed about a dozen or more people lined up by the road just outside of the machsom Hizme, the security barrier at the northern city-line. There were Jews and Arabs, and they were holding signs. We went by too quickly to read them, and nobody, including the bus driver had a clue as to what was the purpose of this demonstration.

So, if you know, I'd appreciate your writing it in the comments here, thanks.
