From the website of the Betar Revisionist Zionist Youth Movement, this article tells the story of Shlomo Ben Yosef, a Betar youth member who was hung by the British in Palestine after participating in a retaliatory attack against local Arabs near Rosh Pina. There is a monument to him in the local Rosh Pina cemetery.
