Afghan refugees travel by taxi on the outskirts of Islamabad on October 21, 2001. The United Nations High Commissioner for Refugees (UNHCR) said it had been told by Pakistani officials at the border that some 5,000 Afghans had flowed into western Baluchistan province at the Chaman crossing on Saturday, a new high after 3,500 streamed over on Friday to escape the US-led strikes. Saturday's movement of Afghans appeared to be the biggest single exodus of civilians since the US strikes began two weeks ago. —REUTERS
