The Vatican has given the go-ahead for Catholics to continue visiting a southern Bosnian village where children reported seeing visions of the Virgin Mary. The Vatican offered its approval for devotion in one of the most contested aspects of Roman Catholic practice in recent years.

After decades, and controversy, the Vatican has authorized public worship at a shrine in Bosnia, where a once tranquil village has become a major pilgrimage site.

The Vatican said Thursday it recognised the shrine of Medjugorje in Bosnia-Herzegovina, without commenting on the Virgin's "alleged messages" to the faithful, who have gathered there in the millions for more than 40 years.

After 40 years of studies, commissions and contradictions, the Vatican finally approved the spiritual devotion of the faithful at the Marian site at Medjugorje, in Bosnia-Herzegovina, in a document issued on Thursday.

The Marian apparitions in Medjugorje stir considerable controversy among the faithful and those outside the Church. Some are convinced of the authenticity of the events, while others have significant doubts.

Catholic worshipers who claim to have seen and spoken to the Virgin Mary at a Bosnian landmark received mixed messages from the Vatican on Thursday after the Church refused to say whether their visions were real — while still supporting worship at the site.
