Cardinal George Pell of Australia died Tuesday evening at the age of 81.

The cardinal underwent a hip replacement surgery on Tuesday, several sources told The Pillar, and reportedly died of complications from the surgery at approximately 8:50 p.m. in Rome.

The hip operation was initially deemed a success, with sources close to the cardinal saying that he had been able to make conversation with nurses in his recovery room, before he suddenly went into cardiac arrest shortly before he died.
