The Vatican said Saturday it has charged five people over a damning leaks scandal at the heart of the Catholic Church, accusing the alleged ringleaders of forming a "brotherhood of crime."

Magistrates on Friday "notified the accused and their lawyers of the charges filed ... for the unlawful disclosure of information and confidential documents," it said in a statement, adding that the trial will begin on Tuesday.

Spanish priest Lucio Angel Vallejo Balda and Italian PR expert Francesca Chaouqui were arrested early this month on suspicion of stealing and leaking classified papers to the media.
