Israeli groups demanded on Tuesday that the government take immediate action to counter the Palestinian Authority’s ongoing building on what is supposed to be a protected nature reserve.

“The Judean Desert has more concrete than mountain goats, a dubious achievement, courtesy of the Palestinian Authority,” charged the Regavim Movement, an NGO dedicated to the protection of Israel’s national lands and resources.

“We expect – we demand – substantial action to restore the fragile desert ecosystem, which has suffered too long from the Palestinian Authority’s rampant illegal construction,” the group said.
