The United Nations urges international donors to pledge up to $10 billion on Tuesday to help Syrians fleeing a decade of civil war in the midst of the COVID-19 pandemic, saying that the need for humanitarian support has never been so great.The event hosted by the European Union will seek $4.2 billion for people inside Syria and $5.8 billion for refugees and their hosts in the Middle East.Some 24 million people need basic aid, a rise of four million over the past year and the highest number yet since a crackdown on pro-democracy protesters by Syrian President Bashar al-Assad in 2011 led to civil war.U.N. aid chief Mark Lowcock says plummeting living conditions, economic decline and COVID-19 result in more hunger, malnutrition and disease. There is less fighting, but no peace dividend.
