The coronavirus is now spreading in Yemen, which announced its first case on Friday. It’s an extremely alarming development in a country suffering the world’s worst humanitarian crisis. Thirty million mostly impoverished people have lost at least half their health care facilities since neighboring Saudi Arabia began a punishing military intervention there in 2015 with U.S. support. The coronavirus news panicked Yemenis and aid groups already fighting mass hunger and a yearslong cholera outbreak. And it highlighted that while world powers like the U.S., Britain and France struggle with the novel coronavirus themselves, they bear significant blame for making places like Yemen especially vulnerable to the new global crisis. Those three countries have given extensive support to the Saudis and allies like the United Arab Emirates (UAE), risking complicity in war crimes, according to United Nations investigators. “We’ve unfortunately played a role … and have a moral responsibility to assist,” said Rep. Ro Khanna (D-Calif.), part of a bipartisan group of lawmakers making the U.S. role in Yemen a top concern in Congress in recent years. Under two U.S. presidents ― Barack Obama, who originally approved assistance to the Saudi-led campaign, and Donald Trump ― America has helped pummel Yemen’s critical infrastructure even as government experts watched the country collapse and sent hundreds of millions of dollars in U.S. aid there. The Saudi-led coalition, whose weapons largely come from the U.S. and other Western producers, attacked at least 32 Yemeni health facilities between 2015 and the end of 2018, killing and injuring medical workers and putting units out of commission, per a recent report by Physicians for Human Rights and the Yemen-based group Mwatana for Human Rights. Until November 2018, the coalition’s planes were also receiving U.S. aerial refueling that enabled longer bombing runs.

As the coronavirus spread worldwide and charities warned it could devastate conflict zones, Trump slashed U.S. aid to Yemen on March 27. The U.S. Agency for International Development said it would suspend at least $73 million earmarked for the north of the country, which is controlled by the Houthis, a rebel militia the Saudis and their partners are fighting. Outside assessments suggested the final cut could be as high as $200 million out of a $746 million budget that provided about one-fifth of the world’s humanitarian support for Yemen. American officials say their new policy will pressure the Houthis to stop interfering with aid deliveries and work. But humanitarian groups view that as a poor and badly timed response to a real problem. “Putting Yemeni lives in the balance through a premature and unilateral funding suspension will not improve the humanitarian situation,” Scott Paul of Oxfam America said in a press release last month. The U.S. “says it will continue supporting life-saving activities even as it eviscerates Yemen’s first and best defense against the defining health crisis of our time. That is simply impossible to understand.” The U.N. urged other donor countries to continue supporting north Yemen as its agencies and marquee charities like the International Rescue Committee, Save the Children and Islamic Relief prepared to limit operations, the UAE-based outlet The National reported. The Houthi-run areas affected include Yemen’s capital and biggest city, Sana’a, large refugee camps and regions that have been particularly badly hit by the Saudi-led coalition’s bombing. Reps. Eliot Engel (D-N.Y.) and Adam Smith (D-Wash.), who chair powerful committees overseeing foreign policy in the House of Representatives, led a letter urging the Trump administration to change course. Administration officials have spoken with congressional staff about programs that might be allowed to continue receiving U.S. funding, but the exemptions they are describing are “very narrow,” a Democratic aide told HuffPost.
