The Yemeni Houthi group described on Tuesday the national charter signed by members of the Southern Transitional Council as a "complete coup" against the Republic of Yemen, Anadolu news agency reported.
"The escalatory step announced by the Transitional Council with a complete coup against the integrity of the Republic of Yemen cannot take place without a green light from the countries of aggression" said Deputy head of the Houthi negotiating delegation, Abd al-Malik al-Ajri, on Twitter, referring to the Arab coalition.
"The preparation for this escalatory step in the context of the negotiating atmosphere and the existing efforts of the Sultanate of Oman during the last period raises questions about hidden intentions that do not reflect good intentions towards the existing understandings and towards Yemen and its unity;" he added.

For several months, regional and international efforts have multiplied to achieve a comprehensive political solution to the crisis in Yemen, including visits by Saudi and Omani delegations to Sana'a, and Gulf tours by the US envoy for Yemen, Tim Lenderking.
Al-Ajri called on the concerned countries to take a clear position on this escalatory step, without specifying specific countries.
On Monday, political factions from the south participating in the meeting signed a "national charter" in Aden, the most notable clause of which included "the restoration of the state of the south with its political and geographical borders according to what was before 22 May 1990," in reference to the unification of the former states of North Yemen and South Yemen.
