^Traubmann, Tamara (2 August 2007). "It's organic, but where was it grown?". Haaretz. Retrieved 4 April 2011. Shortly after human rights lawyer Michael Sfard and Nirit Ben-Horin of Tel Aviv joined the city's organic co-op, they began to suspect that the free-range eggs the group was buying came from a farm on an illegal outpost. The farmer, right-wing activist Avri Ran, lives on the outpost of Gva'ot Olam, south of Itamar in the northern West Bank. Ran, a leader of the Hilltop Youth, is also a local organic farming guru. After Sfard and Ben-Horin confirmed the source of the eggs, they left the co-op.
