The United States has agreed to give the UN another year to wind down its support for African peacekeepers in Somalia, a document showed - a move that gives some breathing space to a force that was fearing quicker cuts, but still leaves its future in peril.

Reuters reported in July that Washington - increasingly frustrated with the fragile administration in Mogadishu - said it would block the UN from supporting the African Union force which props up the government and helps it fight al Qaeda-linked militants.

Analysts have warned that any weakening of the African Union peacekeepers would severely undermine the government there and could exacerbate the political turmoil in a combustible region bordering the Red Sea.

'A REAL RISK OF STATE FRAGMENTATION'

The peacekeepers, known as the AU Support and Stabilisation Mission in Somalia, rely heavily on UN support for essential logistics such as food, water, fuel, medical services and transportation of troops.

The administration of US President Donald Trump, which has pulled back from many international commitments, had told the African Union in a diplomatic note in July that it would use its clout to prevent the UN supporting the peacekeepers from the start of next year. 

In another diplomatic note seen by Reuters and shared with embassies last week, Washington said "the United States is willing to support a 12-month drawdown followed immediately by liquidation" of the UN Support Office in Somalia (UNSOS).

Without that 12-month window, the funding could have stopped at the end of December, when the mandate of that UN office expires. Two diplomatic sources and a Somali government source said the new 12-month countdown would start in January.

A spokesperson for the US State Department told Reuters that Washington would no longer fund or support the UN office in Somalia, whose total budget is around $500-million. 

"We would expect any drawdown processes and timelines to be discussed during UN Security Council deliberations in December," the spokesperson said in a statement. Five diplomatic sources and the Somali government source, speaking on condition of anonymity, confirmed the 12-month deadline.

Somalia's defence ministry, UNSOS and the African ⁠Union Commission did not immediately respond to requests for comment.

FUNDING GAPS

The move will buy Somalia and its partners some more time to find other backers, but does not lift the threat over the peacekeeping force's future.

"AUSSOM is a key pillar of Somalia's state," Afyare Elmi, professor at the City University of Mogadishu, said. "Without it, the country would face a real risk of state fragmentation and disintegration."

Samira Gaid, a regional security analyst, told Reuters the shutdown of UNSOS could spell the end for AUSSOM.

"The AU either (needs) to find alternative logistics arrangements or to draw down and exit," she said.

Financing for the AU mission has become increasingly precarious, leading to a huge funding shortfall.

Washington last year blocked a plan to shift to a financing model that would have seen UN funds cover three-quarters of the peacekeeping mission's $190-million annual budget.

Somalia has been mired in chaos and internal conflict since the fall of autocratic ruler Mohamed Siad Barre in 1991. Islamists have strengthened their control of the countryside and two decades ago, seized the capital before being forced out by a joint Ethiopian and Somali government force.
