Nearly a month into the Middle East war, Lebanon is facing a deepening humanitarian crisis that now risks teetering over into a catastrophe, the UN refugee agency has warned, according to AFP.

Since March 2, more than a million people — one in five residents — have been forced to flee their homes, UNHCR says.

“The situation remains extremely worrying and the risk of a humanitarian catastrophe… is real,” Karolina Lindholm Billing, the agency’s representative in Lebanon, has told reporters in Geneva, speaking from Beirut.
