A nationwide referendum on restricting gay rights in Slovakia has failed to produce a legally binding result after the required number of eligible voters did not turn out.

In Saturday's vote, Slovaks were asked whether they agree to three points: that marriage can only be called a union between a man and a woman; that same-sex partners must be barred from adopting children; and that it's up to parents to decide whether their children receive sex education.

The vote was forced by the Alliance for Family, a social conservative group.

With results from 94 percent of all ballot stations tallied late Sunday, voters in the predominantly Catholic country overwhelmingly voted " ''yes" to the three questions.

But turnout reached only 21.3 percent, far less than the 50 percent needed.
