"The exodus of Syrian refugees accelerated dramatically in recent months, with over 1 million refugees arriving in the first five months of 2013 alone. More than half of registered refugees are children and three quarters of registered refugees are living with local host families and communities in both urban and rural areas. If current trends persist, it can be expected that over 3 million Syrians would have left their country by the end of 2013."
