Half a million Afghans could flee across borders - UNHCR

As a crisis unfolds in the country, a few thousand Afghans have been recorded as entering Iran daily, while traders continue going back and forth from Afghanistan to Pakistan, said Kelly Clements, deputy U.N. High Commissioner for Refugees.

There had been a "small uptick" in the outflow to Pakistan in the recent days, she said.

UNHCR's contingency planning figure of half a million Afghan refugees over the next four months includes departures to Iran and Pakistan and to countries of Central Asia, Clements said.
