The head of the Menashe Regional Council vowed on Tuesday that his constituents would "physically" block the entry of a rightist march into the Israeli Arab town of Umm al-Fahm next Monday.

Ilan Sadeh, the official, branded the march as "explosive."

"Right wing activists are likely to drag the area and the entire state into a violent clash, and bloodshed between Jews and Arabs. We must not let a handful of extremists ruin the fraternal relations between us in the area," he said.

In late October, The High Court agreed to allow right-wing activists Itamar Ben-Gvir and Baruch Marzel lead the march through Umm al-Fahm.

Ben-Gvir had petitioned the court after police rejected a permit for the activists to parade through the city waving Israeli flags.

The initiative has been met by strong opposition in the city and throughout the Arab sector, with MK Jamal Zahalka (Balad) calling it a "legitimization of racism."
