Reuters reports: Syria’s refugee exodus is accelerating and up to 200,000 people could settle in Turkey alone if the conflict worsens, the United Nations warned on Tuesday, increasing pressure for creation of a buffer zone inside Syria.

Turkey has floated the idea of a “safe zone” to be set up for civilians under foreign protection as fighting has intensified in a 17-month-old uprising against President Bashar al-Assad.

Up to 5,000 refugees a day have been crossing into Turkey over the past two weeks while the pace of refugees arriving at a camp in northern Jordan has doubled, heralding what could be a much bigger movement there, the U.N. refugee agency said.

Although there is no sign divided world powers are ready to back a buffer and no-fly zone, as rebels and aid organizations would like, U.N. Security Council foreign ministers are expected to discuss the idea at a meeting on Thursday.

While Turkey could in theory create a buffer zone itself, it has said it is reluctant to go it alone.

Already hosting more than 80,000 refugees, Turkey has warned it could run out of space if the number goes above 100,000.
