Syrian refugees at more than 700,000 as outflow swells - UN

GENEVA, Jan 29 (Reuters) - More than 700,000 Syrian refugees have registered in neighbouring countries or await processing there, as aid workers struggle to keep up with the exodus, the United Nations said on Tuesday.

"We have seen an unrelenting flow of refugees across all borders. We are running double shifts to register people," Sybella Wilkes, spokeswoman for the U.N. High Commissioner for Refugees (UNHCR), told Reuters in Geneva.
