UN Chief to Attend Pakistan-Hosted Meeting on Afghan Refugees Ayaz Gul ISLAMABAD - Pakistan says United Nations Secretary-General Antonio Guterres will visit Islamabad next week to attend an international conference marking 40 years of Afghan refugees' presence in the country. Guterres will deliver a keynote address at the two-day event starting February 17, according to a Foreign Ministry statement. Pakistan officially hosts 1.4 million registered Afghan refugees, making it home to the one of the world's largest refugee populations. More than one million immigrants from Afghanistan are believed to live in the neighboring country without proper documentation. "The U.N. Secretary-General's participation in the international conference is a recognition of Pakistan's exemplary compassion, generosity and resolve in hosting Afghan refugees for the past four decades, and our efforts for peace and stability in Afghanistan," the announcement noted. Delegations from 20 countries will be participating in the conference, which Islamabad is hosting in collaboration with the U.N. High Commissioner for Refugees, or UNHCR. .
