International Conflict: Yemen 
 

World’s worst humanitarian crisis 
24 million people in need, ⅘  of the population
rapid transmission of COVID-19 and renewed fighting have only aggravated the situation, taking humanitarian needs in Yemen to dizzying new heights
obstacles for humanitarian aid: violence against aid workers and humanitarian assets, ranging from murder and assault to arbitrary arrests and theft. A coordinated media campaign in northern Yemen went so far as to incite hate speech and violence against aid organizations. Today, health professionals caring for coronavirus patients and scapegoated groups face threats and attacks
EU has just increased its humanitarian aid for Yemen by another €70 million ($81 million), bringing the total humanitarian funding of the EU for Yemen to €115 million for 2020
 The EU, together with other members of the international community, continues reaching out to parties and stakeholders in support of U.N. efforts to put an end to the war and get the parties to the negotiating table
