ADEN (Yemen) -- Yemen's Prime Minister Ahmed Obeid bin Daghr returned home on Thursday along with a number of ministers to run the country from the southern city of Aden, the country's temporary capital.

The Yemeni PM left Aden two months ago to Saudi Arabia's capital of Riyadh following armed confrontations between his forces and other military units allied with the Southern Transitional Council (STC).

"The legitimate government headed by PM Minister Bin Daghr arrived at Aden's International Airport and will resume its work from presidential compound in the city," a local official said.

"The government came back to Aden after receiving guarantees from the Saudi-led coalition that will be responsible for providing full protection. Disagreements with the STC were also solved," the source added.

In January, the forces loyal to the STC took control of the port city of Aden including the presidential compound and other government headquarters after two days of fighting that left more than 38 people killed and scores others injured.

The pro-STC forces backed by the United Arab Emirates (UAE) also overran the outposts of the Presidential Protection forces allied with the government in Aden during January's fighting.

There have been rising tensions between southern separatist leaders and ministers of the Saudi-backed Yemeni government over control of the southern half of the country.

The two sides had been united throughout Yemen's three-year civil war against the Iranian backed Houthis in the north. However, the conflicts could hinder the efforts of the coalition to control the Iranian expansion plans in Yemen.

The southern port city of Aden is considered as Yemen's temporary capital and the Saudi-backed Yemeni government based itself there since 2015.

Yemen's government, allied with the Saudi-led Arab military coalition, has for about three years been battling Iran-backed Shiite Houthi rebels over control of the country.

The coalition began a military air campaign in March 2015 to roll back Houthi gains and reinstate exiled President Abd-Rabbu Mansour Hadi and his government to the power.

The coalition also imposed air and sea blockade to prevent weapons from reaching Houthis, who had invaded the capital Sanaa militarily and seized most of the northern Yemeni provinces.

UN statistics show more than 10,000 people, most of them civilians, have been killed since the coalition intervened in the Yemeni civil war that also displaced around 3 million.
