The alliance of the main Yemeni opposition parties, the Joint Meeting Parties (JMP) and the Houthi group reached Sunday an a agreement according to both sides will unite efforts to build a civil Yemeni state.
The agreement provides for jointly working to achieve the objectives of Yemen's peaceful revolution for which Yemeni protesters took to streets for nearly eleven months, a statement released on Sunday said.
"Both sides agreed to keep away from all issues that could affect the joint work, recognize the right of opinion and attitudes diversity," the statement added.
"The differences must be resolved away from defamation, accusations of treachery, imposition of views by force and respect of each other opinions."
The United Nations special envoy to Yemen Jamal Benomar had visited the Houthi group in Saada and met with its leader, Abdul-Malik Al-Houthi, demanding them to engage in the political process .
Benomar urged the Houthi group to abandon weapons, form a political party and engage in the political process under the GCC-brokered power transfer deal.
The sit-in squares in which Yemeni protesters camped for nearly 11 months had witnessed divisions between those who support the GCC deal and the Houthis who oppose the inclusion of provisions that grant immunity for the outgoing president Ali Abdullah.
Since pro-democracy protests erupted in Yemen in late January 2011, the Houthi group has been trying to expand their control over the northern provinces of Saada, Amran and Hajja.
Clashes have been continuing between the group and Sunni Salafists in Damaj of Saada, leaving dozens of fighters killed and wounded form both sides.
Houthis had engaged in seven rounds of fighting with Saleh's government over the past six years in northern restive province of Saada.
