The demonstrators also donned long hair and loincloths for the weekly protest against the barrier near the village of Bilin.

They equated their struggle to the intergalactic one portrayed in the film.

Israel says the barrier is needed for its security. Palestinians consider it a land grab.

The protests have become a symbol of opposition. They often end in clashes with Israeli security forces involving stones and tear gas.

The Avatar protest comes a day after the Israeli government began rerouting the enclosure to eat up less of the Palestinian village.
