UN: Afghan Refugees Harassed in Pakistan --- ISLAMABAD — The U.N. refugee agency is warning that Afghan refugees in Pakistan are increasingly becoming victims of extortion, illegal detention and harassment. Pakistan has taken in millions of Afghans since the Soviet invasion in 1979 and has some 1.6 million registered Afghan refugees. -- According to the United Nations High Commissioner for Refugees, hundreds of registered Afghan refugees have recently been illegally swept up and briefly held by Pakistani authorities during security operations. --- Millions of refugee Afghans poured over the border into Pakistan when the Soviet Union invaded Afghanistan in 1979, and more joined them when the Taliban took over in the late 1990s. In the last 10 years, some 3.8 million have been repatriated, but Pakistan still hosts more than one and a half million authorized Afghan refugees. - More, voanews
