Fighters supporting exiled Yemeni President Abd Rabbuh Mansour Hadi battled to take back the northern suburbs of Aden, pushing the Iranian backed Houthi rebel fighters out of their last remaining stronghold of Masheeq in Yemen's southern port city of Aden, sources told Al Jazeera.
The Popular resistance group of pro-Hadi fighters are largely responsible for the push.
Masheeq was the last remaining stronghold in Aden for the Houthi rebels, who over the past two weeks lost all control over Yemen's second largest city.
At least 20 Houthi fighters were killed on Wednesday in the fight to control the city's Masheeq neighbourhood, an area where a palace belonging to exiled President Abd-Rabbu Mansour Hadi is located. Government-allied forces recaptured the palace during the fighting.
The offensive came as Aden's international airport reopened on Wednesday, with a Saudi Arabian plane landing with military supplies.
Exiled Vice President Khaled Bahah said on his verified Facebook account last Friday that Aden had been liberated and that the government making efforts "to restore life" in the city.
The Houthis, however, have consistently rebuffed claims that they have lost control of the city, which they captured large portions of in March.
Several ministers and top intelligence officials of the exiled Yemeni government returned to Aden last week, including the ministers of the interior and transport, a former interior minister, the intelligence chief and the deputy head of Yemen’s parliament assembly.
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.
A ship carrying enough UN aid to feed 180,000 people for a month docked at the Yemeni port of Aden on Tuesday, having previously been prevented from doing so for almost four weeks, World Food Programme spokesman Peter Smerdon said.
"It's the first WFP chartered ship to berth in the port since the conflict erupted in late March," Smerdon said. "We have additional ships chartered which are on standby heading towards Aden carrying more food and fuel."
