An obscure Israeli Arab terrorist organization calling itself the "Galilee Liberation Brigades" has threatened to unleash an unprecedented wave of violence against the Jewish state.

The Galilee Liberation Brigades (GLB) claimed credit last week for a deadly bulldozer attack perpetrated by an Arab resident of Jerusalem. The group also said it was behind the March shooting spree at a Jerusalem yeshiva that left eight young Jewish Bible students dead.

The GLB has previously taken responsibility for the 2003 kidnapping and murder of IDF soldier Oleg Shaichat and the 2007 slaying of Michael Ronkin.

In a weekend interview with the London-based Arabic newspaper Al-Quds Al-Arabi, a man claiming to be the group's leader said the GLB was also responsible for the 2003 disappearance of Dana Bennet, whom the man said is still being held hostage by the group.

Israel has largely refused to recognize the GLB or act against it in any significant way, despite its apparent history of organized ideological violence. The interviewed terror boss said that is a mistake, as his group "seeks to sow terror in the hearts of Zionists," and has already proved itself capable of doing so.

He went on to threaten a new wave of internal terror unlike anything the Palestinian Arabs had hit Israel with, and urged all fellow Israeli Arabs to violently reject the sovereignty and legitimacy of the Jewish state.
