The head of the United Nations refugee agency said on Friday that safe zones would not work inside Syria for people fleeing the country's nearly six-year-old war.
U.S. President Donald Trump said last week he would "absolutely do safe zones in Syria" for refugees escaping violence and that Europe had made a mistake by admitting millions of refugees
"Frankly, I don't see in Syria the conditions" to create successful safe zones, U.N. High Commissioner for Refugees Filippo Grandi said at a news conference in Beirut.
