A former papal diplomat charged with the sexual abuse of boys was taken to hospital and put in intensive care ahead of the opening of his trial at the Vatican.
The trial against Jozef Wesolowski had been scheduled to open today in a Vatican courtroom. Now the judge is expected to immediately adjourn to a later date.
There were no details available immediately from the Vatican about Wesolowski's medical condition.
Wesolowski, 66, faces charges that he sexually abused shoeshine boys in the Dominican Republic and possessed child pornography.
His trial was seen as a high-profile way for Pope Francis to make good on pledges to punish high-ranking churchmen involved in sex abuse of minors, either by molesting children or by systematically covering up for priests who did.
