At least 150 people have been killed in 24 hours of clashes in the Yemeni port city of Hodeidah, medics said Monday, as Britain's top diplomat visited the Gulf seeking to boost international calls for a ceasefire.
Government loyalists supported by a Saudi-led coalition are fighting to oust the Iran-backed Houthi rebels from the strategic Red Sea city, whose docks are a lifeline to 14 million Yemenis at risk of starvation.
Asked about the possibility of a ceasefire, a coalition spokesman told reporters in Riyadh that "the operation is still ongoing," adding that it was meant to pressure the rebels to come to the negotiating table.
A Hodeidah resident reported an ebb in fighting around the city by Monday evening, but U.N. Secretary-General Antonio Guterres warned of a possible "catastrophic situation" if the port is destroyed.
"The fighting must stop, a political debate must begin, and we must prepare a massive humanitarian response to avoid the worst next year," he said.
A military source in the pro-government coalition said the insurgents had pushed back a large-scale assault aimed at moving towards the port, under rebel control since 2014.
In a statement sent via the Telegram messaging app, the Houthis said they had "lured" loyalists up the western coastline of Hodeidah, where the rebels then launched an attack on the troops.
Government forces, led on the ground by Emirati-backed troops, have made their way into Hodeidah after 11 days of clashes, reaching residential neighborhoods in the east on Sunday and sparking fears of street fights that would further endanger civilians trapped in the city.
Residents and government military sources have reported rebel snipers stationed on rooftops in civilian streets in eastern Hodeidah, a few kilometers (miles) from the port on the western edge of the city.
The fighting forced hundreds of terrified medical workers and patients to flee the al-Thawra hospital — Hodeidah's largest public medical facility — as a series of explosions rocked the area on Sunday, Amnesty International said.
A medical worker told Amnesty that they "dodged a hail of shrapnel" as bombardment near the hospital lasted more than 30 minutes.
Enough is enough
The Hodeidah offensive has sparked an international outcry unprecedented in nearly four years of conflict between the Houthis and the Saudi-backed government.
Britain, the United States and France have all called for an end to hostilities. All three countries are major suppliers of arms to Saudi Arabia.
U.S. Secretary of State Mike Pompeo has urged Saudi Crown Prince Mohammed bin Salman, a major ally of Washington, to engage in peace talks.
British Foreign Secretary Jeremy Hunt met with Saudi King Salman and Prince Mohammed on Monday during a visit to the kingdom to press its rulers to support UN efforts to end the conflict.
Hunt also flew to the United Arab Emirates, a key pillar of the Saudi-led coalition, to meet the crown prince of Abu Dhabi.
In France, Foreign Minister Jean-Yves Le Drian said it was time "the international community said enough is enough.
"There will be no victor in this war," Le Drian told France 2 TV.
Aid groups fear for the safety of hundreds of thousands of people living in Hodeidah — and for millions of others dependent on its port for what little food and humanitarian aid trickle into impoverished, blockaded Yemen.
A military official in Hodeidah on Monday confirmed seven civilians had died, without giving further details.
A 15-year-old boy died last week of shrapnel wounds in Hodeidah, Save the Children said.
Medics in hospitals across Hodeidah province reported 111 rebels and 32 loyalist fighters killed overnight, according to a tally by AFP.
Sources at the Al-Alfi military hospital, seized by the rebels during their 2014 takeover, said charred body parts had been delivered there overnight. Military sources confirmed that the Saudi-led alliance had targeted the rebels with multiple airstrikes.
The rebels have begun to evacuate their wounded to Sanaa, the capital, which the Houthis seized during a 2014 takeover that included a string of ports on Yemen's coastline.
Saudi Arabia and its allies intervened in the Yemeni government's fight against the Houthis in 2015, triggering what the U.N. now calls the world's worst humanitarian crisis.
Nearly 600 people have been killed since clashes erupted in Hodeidah on November 1, ending a temporary suspension in a government offensive to take the city that began in June.
The coalition has come under intense international pressure to end the conflict, particularly following the killing of Saudi journalist Jamal Khashoggi, an ardent critic of Prince Mohammed, in his country's consulate in Istanbul on October 2.
Multiple countries, including Germany and Norway, have announced the suspension of arms sales to Saudi Arabia after Khashoggi's killing.
The United Nations' Yemen envoy, Martin Griffiths, is pushing for peace talks between the Houthis and the government by the end of the year.
The United States, which for years provided military training and aerial refueling for the Saudi-led coalition, on Saturday announced it would end its inflight refueling support for the alliance.
The alliance accuses Iran of smuggling arms to the Houthis through Hodeidah port. Tehran denies the charges.
