(CNN)An operation to recapture the northwestern Yemeni port city of Hodeidah got underway at dawn Wednesday, potentially putting a quarter of a million people at risk.
Saudi-led forces begin attack on Yemen port city, ignoring UN warnings
The Saudi-led coalition launched ground attacks on the city's airport and other neighborhoods in the southeastern part of the city, with air and naval support, General Mohsen Al Khosrof of the Yemeni National Army (YNA) told CNN.
The YNA and the coalition are fighting on behalf of the internationally recognized government, which is trying to squash an insurgency by Iran-backed Houthi rebels.
A UAE military ship has been attacked by Houthi rebels and is currently on fire in the Red Sea off the coast of Hodeidah, according to two senior Yemeni-Houthi military commanders.
UAE state media has also reported that four Emirati soldiers had died fighting in Yemen, though the article did not specify whether their deaths are related to the attack on the ship.
Last week, the UN said that in a worst-case scenario as many as 250,000 people could be killed in an offensive against Hodeidah.
"I am extremely concerned about military escalation in #Hodeida & their humanitarian & political impact. We're in contact with parties to avoid further escalation. We call on them to exercise restraint & engage with political efforts to spare Hodeida a military confrontation," the office of the UN's Yemen envoy Martin Griffiths said in a tweet on Monday.
The city, which is currently under rebel control, is considered a lifeline for the country's war-ravaged population. About 90% of food, fuel and medicines consumed in Yemen is imported, with 70% of that coming through Hodeidah, according to the UN.
"Taking over Hodeidah could be called an act of madness in every meaning of the word because Hodeidah is (a) city full of civilians and it holds the main artery for all Yemenis, in the North and in the South," Sanaa resident Aly Al-Mahdy said.
Another resident in the capital, Nouran Mohammed, said that it would "result in a humanitarian disaster."
Recapturing the port would deprive the Houthis of access to the Red Sea, possibly ending the virtual stalemate between the rebels and the government. The Houthis control parts of northern Yemen, including Hodeidah and the Yemeni capital, while the government controls much of the south.
"The liberation of the port of Hodeidah is a turning point in our struggle to take back Yemen from the militias that hijacked it to carry out foreign agendas," the government said in a statement on Wednesday.
The United Arab Emirates, which is part of the coalition, on Wednesday called on the international community to pressure the Houthis to abandon the port, and said it remains open for shipping.
"The international community must pressure the Houthis to evacuate Hodeida & leave the port intact. Their use of land & sea mines shows a cruel & callous disregard for Yemeni lives," the UAE's Minister of State for Foreign Affairs Anwar Gargash said in a tweet.
In a statement, Emirati Minister of State Reem Al Hashimy said the coalition has prepared a "large-scale and comprehensive surge plan for the rapid delivery of humanitarian aid."
Saudi Arabia's ambassador to the US, Khalid bin Salman, tweeted that the offensive was "critical in light of the growing threat that the Iranian backed Houthi militia poses to the maritime security of the red sea."
In a series of tweets on Wednesday, he added: "The Houthi's continued obstruction with regards to Hodeidah is due to their use of the port to raise revenues through looting, extortion, and illegal taxation imposed on commercial ships to finance and sustain their military aggression against Yemen and neighboring countries."
Thousands of people have died in Yemen's war. In 2015, Houthi rebels took over large swaths of territory prompting a coalition intervention. The conflict has spiraled into what the UN has dubbed "the world's worst humanitarian crisis."
On Monday, the UN Security Council held an emergency meeting on Hodeidah after the UAE asked the United Kingdom to tell aid agencies to leave the port city. The aid agencies were told to evacuate by Tuesday night.
Speaking ahead of Monday's emergency meeting called by the UK, Karen Pierce, Britain's ambassador to the UN, said: "The important thing is that (Hodeidah) is kept open and it is kept functioning because it is the major route in for these commercial supplies."
UN Humanitarian Chief Mark Lowcock also warned about the potential consequences of an operation.
"Seven million people are completely reliant every month on food and other assistance from humanitarian organizations so Hodeidah is absolutely central to the preserving of life," Lowcock said at a press briefing on Monday.
"If for any period, Hodeidah were not to operate effectively, the consequences in humanitarian terms would be catastrophic."
However, the United States, which previously stood against the offensive, appears to have offered tacit agreement. Officials issued a statement Monday that Yemen analyst Adam Baron described as a "yellow light" for the Yemen offensive.
"I have spoken with Emirati leaders and made clear our desire to address their security concerns while preserving the free flow of humanitarian aid and life-saving commercial imports," said US Secretary of State Mike Pompeo in a press statement Monday.
The offensive risks plunging the country into further violence as the coalition tries to wrest control of the strategic city from the rebels. A coalition takeover would tip the conflict in favor of Saudi Arabia and its allies.
"This offensive represents a huge escalation in the conflict ... a lot of it depends on how Hodeidah falls. If the Houthis dig in, this could be a bloody street battle comparable to Aleppo," Baron, the analyst, said.
But "there is the opportunity for a Houthi withdrawal and for the coalition to force a Houthi retreat," Baron added.
"This is something that could be extremely high-risk and could cause a lot of humanitarian disruption ... there's a reason why you're seeing so much opposition in some quarters."
