A UN agency has said it will soon be unable to provide "life-saving" aid to Syrian refugees in Jordan and other countries due to funds running out."The needs are rising exponentially and we are broke," said Marixie Mercado, a spokeswoman for children's charity Unicef.
Some 1.2 million Syrians have fled since the uprising began in March 2011.
Around 385,500 have escaped to Jordan, with figures set to triple by the end of the year, Ms Mercado said.
This would bring the number of Syrian refugees there close to 1.2 million - the equivalent of one-fifth of Jordan's total population.
"Since the beginning of year, more than 2000 refugees have streamed across the border [into Jordan] every day," Ms Mercado told reporters at a UN news conference in the Swiss city of Geneva on Friday.
"We expect these numbers to more than double by July and triple by December."
Many of the refugees are children, the spokeswoman added.
