After months of working from exile, the prime minister of the Yemeni government returned to the southern port city of Aden in a step to restore the government in Yemen.
Seven Yemeni ministers came back to Aden with Bahah, who is also a vice president, government spokesman Rajeh Badi said.
Yemeni fighters loyal to exiled President Abd Rabbuh Mansour Hadi - backed by Saudi-led coalition airstrikes - took back the city of Aden from the Iranian-backed Houthi militants in July.
"Khaled Bahah and the ministers who arrived with him are in Aden to stay permanently," Badi said.
Several Yemeni ministers have arrived in Aden coming from Saudi Arabia, weeks after the city was retaken from the Houthis.
On August,1, Bahah made a short visit to Aden but then went back again to the kingdom. After Houthi militants retreated from the city of 1 million people, chaos spread there.
But some local officials have said, according to Reuters, that 300 police officers have returned to work in Aden since July.
On Tuesday, pro-Hadi fighters captured two strategic hills in the rebel stronghold of Sirwah in the province of Marib, on the route to the capital city of Sanaa.
War-torn Yemen has been suffering since March, when the Houthis seized the country's capital Sanaa and advanced towards Aden, forcing Hadi and his government to flee to Saudi Arabia.
A coalition comprising of 10 Arab countries has been intervening in Yemen since March 26, battling the Houthis with the aim of restoring the exiled government of Yemeni President Abd Rabbuh Mansour Hadi.
The six-month-long war in the country has triggered an unprecedented humanitarian crisis in Yemen. The UN has declared the situation in Yemen to be a level-three humanitarian emergency, the highest on its scale, after about 80 percent of the country’s population fell into dire need of humanitarian aid.
Twenty million people in the country are in need of aid, 13 million are facing food shortages and 9.4 million are having difficulties accessing drinking water.
At least 4,000 civilians have been killed since the coalition began its bombing campaign in support of the exiled government last March and at least 1.3 million have been forced to flee their homes during the conflict.
