Vice President and Premier Khalid Bahah and a number of ministers and officials within the cabinet returned to Yemen's temporary capital of Aden on Monday, local officials said.
They came back from the Saudi capital Riyadh and the United Arab Emirates where they have been staying for months.
They have come back to resume duties from Yemen with priority to be given to restoring security and stability as well as rebuilding the regions that had been damaged and destroyed during the battles with the Houthi militants, the officials said.
Bahah and the government left Aden months ago after their residences along with the residence of UAE forces guarding them came under ISIS-claimed rocket attacks.
President Abd Rabbuh Mansour Hadi and the government fled to Saudi Arabia early last year after they had been ousted and then released from house arrest by the Houthi militants.
President Hadi returned to Aden after the first return of Bahah and ministers to Aden in September.
Meanwhile, Aden is still facing huge security challenges including a rise of targeted killings and presence of militant groups such as Al-Qaeda ISIS.
In middle, eastern and northern regions, the battles between the pro-government and Houthi forces are continuing coinciding with escalating airstrike by the Saudi-led coalition.
The government with support from the coalition retook southern regions from the Houthis in mid-2014. The coalition launched a military intervention in Yemen in late March.
Still, some Houthi militants are in some areas of the province of Shabwa where sporadic battles have been reported recently.
