SANAA: Yemeni political factions resumed UN-brokered talks on Monday with the Shiite militia that grabbed power last week, but one group walked out underlining the complexity of the crisis.

“We will not return to the table of negotiations,” Nasserite party chief Abdullah Nooman told reporters as he left the closed-door meeting in the capital Sanaa.

Nooman charged that the Houthi militia was insisting on holding talks based on the “constitutional declaration” under which they took over the government on Friday.

The Houthis “have threatened to take measures” against the Nasserite party and Al-Islah, a Sunni party whose supporters have battled the Shiite militia, he added.

Al-Islah and the Nasserite party have both rejected the Houthi power grab and called for a return to political dialogue.

On Friday, the militia dissolved Parliament and created a “presidential council” in a move it said was designed to fill a power vacuum after Western-backed President Abed Rabbo Mansour Hadi and Prime Minister Khalid Bahah resigned last month.

The militia also sought to portray the move as a way of heading off the threat from Al-Qaeda, which has a strong presence in southern and eastern Yemen.

UN envoy Jamal Benomar told reporters Sunday that Shiite militia leader “Abdelmalek Al-Houthi and all political parties in Yemen have agreed to resume dialogue... which will begin tomorrow (Monday).”

Benomar called on all political leaders to “take up their responsibilities and achieve consensus” in order to reach a “peaceful solution.”

On Monday, he addressed the meeting at a Sanaa hotel saying: “The dialogue resumes from where it stopped on Thursday.”
