Facebook Inc.’s top privacy regulator in the European Union said it’s looking into a leak over the weekend of the personal data of more than half a billion users of the social media service.

The Irish Data Protection Commission is trying to “establish the full facts” since the weekend and so far “received no proactive communication from Facebook,” the regulator said in a statement on its website on Tuesday. It said the tech company assured it that “it is giving highest priority to providing firm answers” to the authority.
