The Bethnahrin National Council or Mesopotamia National Council (Classical Syriac: ܡܘܬܒܐ ܐܘܡܬܝܐ ܕܒܝܬܢܗܪܝܢ, romanized: Mawtbo Umthoyo d'Bethnahrin, MUB), formerly the Bethnahrin Freedom Party (Classical Syriac: ܓܒܐ ܕܚܐܪܘܬܐ ܕܒܝܬܢܗܪܝܢ, romanized: Gabo d'Ḥirutho d'Bethnahrin, GHB) and the Patriotic Revolutionary Organization of Bethnahrin (Classical Syriac: ܛܘܟܣܐ ܕܘܪܢܝܐ ܡܬܢܝܐ ܕܒܝܬܢܗܪܝܢ, romanized: Ṭukoso Dawronoyo Mothonoyo d'Beth Nahrin, PROB) is a militant socialist Assyrian-Syriac party in the Dawronoye movement, whose stated goal is autonomy for Assyrian-Syriac people, either as an independent state[3] or some other structure, in Bethnahrin, the Assyrian homeland.

The Patriotic Revolutionary Organization of Bethnahrin was formed in the 1990s by Assyrian-Syriac nationalists who previously fought within the PKK against Turkey.

[4] Three days later a second attack was carried out by the group in which several of Massoud Barzani's fighters were killed when a Peshmerga army truck driving on a bridge between Qasre and Haji Omeran was blown up by the PROB.

The group claimed both attacks were to avenge the death of Assyrian woman Helene Aloun Sawa, who was raped and killed by the Peshmerga.

According to Wladimir van Wilgenburg, the GHB's founder, Numan Ogur, was kidnapped in 2003 after an attempt to try to leave the organization.
