More than four million Syrians have fled their country’s civil war, the United Nations said on Thursday, with many now despairing that they will ever return to their conflict-wracked homeland. “We don’t think about going back to Syria. What we think about from day to day is how to keep our children alive,” said Yassin al-Ali, a Syrian refugee living in northern Lebanon. Ali, 45, lives with his wife and three children in an informal refugee camp, that has no electricity or drinking water, on agricultural land were many refugees work long hours to eke out a meagre salary. Syria’s conflict began with anti-government protests but spiralled into a war after a regime crackdown. It has since claimed more than 230,000 lives, according to the Syrian Observatory for Human Rights. The UN refugee agency UNHCR said Thursday that the number of Syrian Refugees now stands at 4,013,000 people, with another 7.6 million displaced inside the country. “This is the biggest refugee population from a single conflict in a generation,” UN refugee chief Antonio Guterres said in a statement. “It is a population that needs the support of the world but is instead living in dire conditions and sinking deeper into poverty.” Most Syrian Refugees are sheltering in neighbouring countries like Turkey, Lebanon, Jordan and Iraq. UNHCR estimated that $5.5 billion are needed this year to help Syrian Refugees and the increasingly overwhelmed communities hosting them.
