STOCKHOLM (AFP) - Twins born in Indonesia and put up separately for adoption, have been reunited after finding each other on Facebook, living just 40km apart in southern Sweden, three decades later. Non-identical twins Emilie Falk and Lin Backman - strangers until last year - were separated nearly 29 years ago. According to a DNA test the pair had done two months after reuniting in January last year, and which they shared with AFP, there is a 99.98 per cent chance of them being sisters. A complex string of events led up to that revelation. Both were adopted from an orphanage in Semarang in northern Indonesia by Swedish couples, but there was no mention in either of their documents of the fact that they had a twin.
