SANAA, Yemen (AP) -- Saudi-led forces fought to retake the international airport of Yemen's rebel-held port city of Hodeida from the Shiite Houthi rebels, Yemeni officials and witnesses said on Saturday, as combat intensified for the starving nation's main gateway for food shipments.
With battles raging at the southern side of al-Hodeida International Airport, the military of Yemen's exiled government said it had entirely seized the facility, and that engineers were working to clear mines from nearby areas just south of the city of some 600,000 people on the Red Sea.
"The armed forces which are supported by the Arab coalition have freed the al-Hodeida International Airport from the Houthi militias and the engineering teams have started to clean the airport and its surroundings from mines and bombs," the military said on its official Twitter account.
Other government officials and witnesses later said coalition forces had not yet fully taken control of the airport. They said fighting was heavy just outside the airport gates.
Sadek Dawad, spokesman of the Republican Guards force loyal to the Saudis, said government forces had battled onto the airport grounds.
Dawad also said the southern gate of Hodeida city was captured by pro-coalition forces.
"The military operations to liberate the city of Hodeida will not be stopped until we secure the city and its strategic port and that won't last too long," he told The Associated Press.
Yemen's Shiite rebels known as Houthis, who hold the country's capital of Sanaa, did not immediately acknowledge losing the airport.
The Houthi-run Al Masirah satellite news channel aired footage it described as being from near Hodeida showing a burned-out truck, corpses of irregular fighters and a damaged Emirati armored vehicle. The Iranian-aligned fighters rifled through a military ledger from the vehicle before chanting their slogan: "Death to America, death to Israel, damn the Jews, victory to Islam!"
Yemeni officials and witnesses said forces from the United Arab Emirates-backed Amaleqa brigades, backed by air cover from the Saudi-led coalition, were heading to eastern Hodeida province to attempt to cut off the main road that links it with the capital, Sanaa.
The officials said if government forces capture the Kilo 16 Road they will trap the rebels in Hodeida and the western coast and prevent them from receiving supplies from the capital. The rebels are then expected to have no choice but to head to the northern province of Hajjah.
The officials spoke on condition of anonymity because they were not authorized to brief media and the witnesses for fear of reprisals.
The Norwegian Refugee Council said humanitarian agencies cannot reach the southern part of Hodeida as fighting escalated. It said in a statement that heavy airstrikes by the Saudi-led coalition have moved confrontation lines deeper to the south.
United Nations special envoy Martin Griffiths, meanwhile arrived in Sanaa in an effort to broker a cease-fire.
The Saudi-led coalition began its assault Wednesday on Hodeida, the main entry for food into a country already on the brink of famine. Emirati forces are leading ground forces mixed with their own troops, irregular militiamen and soldiers backing Yemen's exiled government. Saudi Arabia has provided air support, with targeting guidance and refueling coming from the U.S.
International aid groups and the UN cautioned the Saudi-led coalition from launching the assault. Their fear is that a protracted fight could force a shutdown of Hodeida's port at a time when a halt in aid risks tipping millions into starvation. Some 70 percent of Yemen's food enters via the port, as well as the bulk of humanitarian aid and fuel supplies. Around two-thirds of the country's population of 27 million relies on aid and 8.4 million are already at risk of starving.
For its part, the Saudi-led coalition says it had no choice but to launch the assault as the port provided millions of dollars for the Houthis through customs controls. They also accuse the Houthis of using the port to smuggle weapons through, something a U.N. panels of experts described in January as "unlikely" as incoming ships require U.N. permission and are subject to random searches.
The U.N. and Western nations say Iran has supplied the Houthis with weapons, from assault rifles to the ballistic missiles they have fired deep into Saudi Arabia, including at the capital, Riyadh.
The coalition has blocked most ports, letting supplies into Hodeida in coordination with the U.N. The air campaign and fighting have disrupted other supply lines, causing an economic crisis that makes food too expensive for many to afford.
Aid agencies and the U.N. evacuated international staff from the city ahead of the offensive. Some of the wounded able to flee are driving onto Aden, some 315 kilometers (195 miles) away, after being stabilized at a hospital in Mocha on the way, the aid group Doctors Without Borders said. The local hospital in Hodeida already is struggling to help the wounded, the group said.
Thousands remain besieged in the city and around the airport due to the fighting.
"Families are trapped inside and it is difficult leaving as they are coming under airstrikes and bombardment by both parties of the war," relief worker Saber Wasel told The Associated Press. "It was a hard night for citizens because of the intensity of the strikes and gunfire."
The Houthis seized control of Sanaa in September 2014, later pushing south toward the port city of Aden. The Saudi-led coalition entered the conflict in March 2015 and has faced criticism for a campaign of airstrikes killing civilians and destroying hospitals and markets.
The Houthis meanwhile have laid land mines killing and wounding civilians, targeted religious minorities and imprisoned opponents.
