ADEN (Reuters) – The Saudi-led coalition has massed thousands of troops near Yemen’s main port city of Hodeidah, local military sources said on Wednesday, in a move to pressure Iranian-aligned Houthi insurgents to return to U.N.-sponsored peace talks.

The United States and Britain have called for an end to the 3-1/2-year war that has driven impoverished Yemen to the verge of famine, raising pressure on Saudi Arabia as it faces a global outcry over the murder of prominent Saudi journalist Jamal Khashoggi in the Saudi consulate in Istanbul on Oct. 2.

The military alliance of Sunni Muslim states led by Saudi Arabia and the United Arab Emirates has deployed around 30,000 forces south of Houthi-held Hodeidah and near its eastern entrance, pro-coalition Yemeni military sources told Reuters.

“Thousands of Yemeni soldiers trained by the coalition have been sent to the outskirts of Hodeidah in addition to modern weaponry including armored vehicles and tanks…in preparation for a big operation in coming days,” said one source.

Residents told Reuters that the Houthis had also deployed forces in the center of Hodeidah city, at the port and in southern neighborhoods in anticipation of an onslaught.

The coalition and the Houthis have not commented on the military movements.

The U.N. special envoy to Yemen is trying to salvage peace talks that collapsed in September, raising the risk of a renewed assault on the Red Sea city, the country’s main port and a lifeline for millions of Yemenis reliant on humanitarian aid.

Envoy Martin Griffiths welcomed a call by U.S. Secretary of State Mike Pompeo on Tuesday for a cessation of hostilities ahead of U.N.-led negotiations scheduled to begin next month.

Britain also endorsed the U.S. call to end the fighting, which has killed more than 10,000 people, according to available U.N. figures, and triggered the world’s most urgent humanitarian crisis.

“We remain committed to bring the Yemeni parties to the negotiations table within a month. Dialogue remains the only path to reach an inclusive agreement,” Griffiths said in a statement issued on Wednesday.

“I urge all concerned parties to seize this opportunity to engage constructively with our current efforts to swiftly resume political consultations to agree on a framework for political negotiations, and confidence-building measures,” he said, listing support for the central bank and a prisoner swap.

DIRE SITUATION

The Western-backed Arab alliance intervened in Yemen’s war, widely seen as a proxy conflict between Saudi Arabia and Iran, in 2015 to restore the internationally recognized government.

But after seizing the southern port city of Aden and some towns on the western coast, the alliance has made little gains in a costly war to unseat the Houthis, who hold the most populous parts of Yemen including the capital Sanaa.

The United Nations aid chief told the Security Council earlier this month that half the population of Yemen – some 14 million people – could soon be on the brink of famine.

Aid groups warned of deteriorating conditions in the Arabian Peninsula country.

“The recent increase in military activity in…Hodeidah threatens the security of our life-saving operations,” World Food Programme spokesman Herve Verhoosel said on Wednesday.

He said the WFP has enough cereals to assist 6.4 million of the neediest Yemenis for 2-1/2 months, with the aim to reach 8 million.

Red Cross spokeswoman Sara Alzawqari said that an estimated 3,200 families – some 22,000-28,000 people – were in dire need of basic necessities including food, water and shelter in Hodeidah, many having fled fighting in rural areas.

The UAE and Saudi Arabia have repeatedly said that taking control of Hodeidah would force the Houthi movement to the negotiating table by cutting off its main supply line.

But a previous offensive on the heavily-defended city in June failed to accomplish any gains and the coalition halted the fighting to give U.N. peace talks in Geneva a chance.

The talks were abandoned when the Houthi delegation failed to show up. The Houthis accused the coalition of blocking the group’s team from traveling, while the Yemeni government accused the Houthis of trying to sabotage the negotiations.
