Mr. Gareth Thomas:
The most recent estimate by the United Nations High Commissioner for Refugees (UNHCR), of Afghan refugees in Pakistan is 1.6 million individuals. The number, however, is difficult to assess accurately as there has not been a registration since 1995. In addition, there are significant numbers of Afghans in Pakistan who are not refugees. In Iran UNHCR's estimate is 1.9 million. Here most of the Afghan refugees are registered, although there may be a significant margin of error.
