SARAJEVO, OCT 12: The world's six billionth inhabitant - by United Nations count - was born in Sarajevo's Kosevo hospital at 00.01 am Tuesday as a yet unnamed boy weighing 7.81 pounds.Maternity department chief Ivriz Bukvic said mother and child were doing well, and that the birth had been without problems.The mother, Fatima Mevic, and her husband, Jasminko Mevic, are Bosnian Muslims who live in Visoko, some 20 kilometres northwest of the Bosnian capital. It is the first child for Fatima, 29.UN Secretary-General Kofi Annan arrived in Sarajevo on Monday for a two-day visit to greet the new arrival.The move is purely symbolic as demographers agree the six billionth human being is more likely to be born in Asia than in Bosnia, although no one can tell with precision when and where the world population will cross the new threshold.
