The Saudi-led coalition fighting the Iran-aligned Houthis in Yemen moved on Monday to work out a ceasefire with its nominal allies in the south of the country who turned on each other in a power struggle, fracturing the military alliance.
Saudi Arabia and the United Arab Emirates, the main powers in the Arabic coalition, formed a joint committee to oversee a ceasefire between southern separatists and government forces in the provinces of Abyan and Shabwa, said a joint statement carried on state media.
"Internal dialogue, and not fighting, is the only way to resolve internal Yemeni differences," Saudi vice minister of defence, Prince Khalid bin Salman, tweeted on Monday.
"We are working with the UAE for security and stability in Aden, Shabwa and Abyan and ... to unify ranks and voices to combat terrorist threats, whether from the Iran-backed Houthis or from al Qaeda and Daesh (Islamic State)," Khalid said.
Separatists forces early this month took over the southern port of Aden, interim seat of President Abd-Rabbu Mansour Hadi's government, and last week extended their reach to the capital of nearby Abyan. Southern fighters and government forces have also clashed in the oil producing Shabwa province.
Government forces captured Shabwa's capital, Ataq, over the weekend after southern forces lost control of the main military compound there.
On Monday, Hadi's forces were moving towards Balhaf, site of Yemen's liquefied natural gas terminal, where southern forces have a major military base, military sources said. Balhaf is run by France's Total but it has been in a preservation mode since 2015 when the civil war reached the south of the country.
Both sides are part of the Saudi-led coalition that intervened in Yemen in 2015 against the Houthis, who ousted Hadi's government from power in the capital Sanaa in late 2014.
Summit in the Kingdom
The Southern Transitional Council (STC), which seeks self-rule in the south, seized control of Aden after accusing a party allied to Hadi of being complicit in a Houthi attack on southern forces.
The violence in the south complicated U.N. efforts to implement peace deals elsewhere in the Arabian Peninsula state and pave the way for negotiations to end a war that has killed tens of thousands and pushed Yemen to the brink of famine.
The Saudi-UAE statement urged all parties to cooperate with the joint committee to disengage and redeploy troops and reiterated a Saudi call for a summit in the kingdom to resolve the standoff.
It also stressed the need to preserve "the interests, security, stability, independence and territorial integrity of the Yemeni people under the leadership of the legitimate president of Yemen."
Hadi’s government has said it would not participate until separatists ceded control of sites they had seized.
The separatist STC has said it would not hand over control of government military camps in Aden and other areas until the Islamist Islah party, a backbone of Hadi's government, and northerners are removed from positions of power in the south.
The Houthis, who have recently stepped up missile and drone attacks on Saudi cities, point to Aden as proof that Hadi, who resides in Riyadh, is unfit to rule. The movement denies being a puppet of Iran and says it is fighting a corrupt system.
