The United Nations yesterday said it was struggling to cope with an "unrelenting flow" of families fleeing Syria, as the number of documented refugees topped 700,000.
Sybella Wilkes, a spokeswoman for the UN refugee agency, UNHCR, said the number of families seeking refuge across the border had risen dramatically, with more than 3000 crossing into Jordan on Monday alone.
Some 712,000 refugees had registered with the UNHCR or were awaiting registration yesterday, though many are wary of making themselves known.
An upsurge of violence in Deraa has driven entire villages to leave, according to officials in Jordan, where a new refugee camp is being hastily built.
In Lebanon, where there are no official camps, refugees construct tents in shanty communities or take shelter in garages and empty shops.
