A Romanian priest has been jailed for 14 years for conducting an exorcism that led to the death of a nun who he believed was possessed by devils.

Irina Cornici, 23, died after being starved and chained to a cross at a secluded convent in the north-east.

In 1999, when the Vatican issued its first new guidelines since 1614 for driving out devils, it urged priests to take modern psychiatry into account in deciding who should be exorcised.
