In a statement released on Sunday, the UN Office for the Coordination of Humanitarian Affairs said 4,458 households had been displaced from their homes in Hudaydah since June 1.
It added that at least 36 displaced families had already lost their entire livelihood as their farms were damaged in airstrikes by Saudi-led airstrikes earlier this month, Presstv Reported.
After nearly a month of sporadic clashes between fighters of the popular Houthi Ansarullah movement and the Saudi-led coalition coupled with the militia loyal to Yemen’s former President Abd Rabbuh Mansur Hadi in the volatile province, the latter two launched a major assault on Wednesday to take the Houthi-held Hudaydah, a densely populated city and the war-torn country's most vital port.
The Houthi movement, which is a significant aid to the Yemeni army in defending the country against the invading forces, has been running state affairs in the absence of an effective administration during the past three years.
The invasion of Hudaydah has already triggered fears of a fresh humanitarian crisis in a country where more than 22 million people are in need of aid, including 8.4 million who are at risk of starvation.
Meanwhile, Yemen's official Saba news agency reported that warplanes belonging to the Saudi-led coalition had conducted at least five airstrikes against Hudaydah as Hadi’s militia launched their ground attacks against the port city, a lifeline to millions of Yemenis.
On Saturday, Hadi’s ground forces, backed by Emirati and Sudanese troops, reportedly surrounded Hudaydah International Airport.
“We have lived in a state of terror for three days because we are in a neighborhood close to the airport,” said resident Khaled Ateeq, 38.
According to the Ansarullah news portal, Saudi-led warplanes hit the airport with at least 20 airstrikes on Sunday.
Additionally on Sunday, Martin Griffiths, the UN envoy for Yemen, was believed to be busy pushing a truce deal between the two sides on his second day of stay in the Yemeni capital of Sana’a. The envoy, however, did not make any statement on his arrival at the capital’s international airport on Saturday.
Yemen’s Arabic-language al-Masirah television network reported that Houthi fighters, backed by the Yemeni army and the Popular Committees, had managed to destroy 44 military and armored vehicles of the so-called coalition and Hadi’s militia.
In a separate report, an unnamed Yemeni military source said the Yemeni army had targeted a newly-built Saudi military base in the kingdom’s southern province of Jizan with the domestically-manufactured short-range Badr-1 ballistic missile.
The report, citing the source, said that the projectile had hit the target with great precision, inflicting heavy damage upon the base.
Saudi Arabia and its allies launched the war on Yemen in March 2015 to install the former Saudi-backed Hadi regime.
The Yemeni Ministry of Human Rights announced in a statement on March 25 that the war had left 600,000 civilians dead and injured until then.
The war and an accompanying blockade have caused famine across Yemen. The United Nations says a record 22.2 million people are in need of food aid, including 8.4 million threatened by severe hunger.
The Saudi aggression has also taken a heavy toll on the country's facilities and infrastructure, destroying many hospitals, schools, and factories.
Since 2016, the impoverished nation has also been grappling with a deadly cholera outbreak, which has already killed thousands of people.
Several Western countries, the US and the UK in particular, are accused of being complicit in the aggression as they supply the Riyadh regime with advanced weapons and military equipment as well as logistical and intelligence assistance.
