Syrian refugees plead with U.S. secretary of state in Jordan July 18, 2013 -- Updated 1058 GMT (1858 HKT) Syria's refugee crisis NEW: Refugees vent their anger to John Kerry over a lack of international action The Za'atri camp in Jordan is home to roughly 120,000 refugees fleeing the civil war Most of them are women and children Obama's U.N. ambassador nominee called U.N. efforts on Syria a "disgrace" Wednesday (CNN) -- The world has forsaken their homeland, a group of Syrian refugees told John Kerry. The secretary of state visited a U.N. refugee camp in Jordan on Thursday, a day after an Obama administration official lambasted the United Nations over its response to the crisis. The six uprooted Syrians who sat down with Kerry at the Za'atri camp were angry. He told them he was sorry for their suffering and asked them to speak their minds. They did. Please set up a no-fly zone to stop Bashar al-Assad's bombardments, the five women and one man pleaded repeatedly. Where is the international community? What are you waiting for?" asked a woman who did not give her name. At least impose an embargo. "I wish it was very simple," Kerry told them. As you know, we've been fighting two wars for 12 years. He let them know that the United States is fatigued from Iraq and Afghanistan. They begged him to set up buffer zones and to stop the influx of weapons from Iran to aid al-Assad. Stop Hezbollah's troops from Lebanon from coming to fight side by side with his troops against the rebels, a woman pleaded. Kerry told her he was "not happy" either with what Iran and Hezbollah were doing. Lucy Liu: Syria's children deserve chance to be kids again The Za'atri camp is home to roughly 120,000 refugees fleeing the civil war in Syria. Most of them are women and children. The U.S. has donated more than $800 million in humanitarian aid to the U.N. for Syria. More than one-fifth is for refugees in Jordan. The U.N. estimates that more than 93,000 people have died in Syria's civil war. On Wednesday, President Obama's nominee as U.N. ambassador, Samantha Power, during her confirmation hearings called U.N. efforts on Syria a "disgrace." After his visit, Kerry climbed into a helicopter and flew back to Amman, Jordan's capital. Before he left, one of the Syrian women told him that the refugees might not be there when he came back. If no help comes from the outside, she said, they will return to Syria to fight al-Assad with knives.
