Pope Francis' death Monday at the age of 88 comes after the Catholic leader experienced a number of health issues in recent years.
Francis died at 7:35 a.m. Monday at his residence, the Vatican said. His official cause of death was not immediately revealed.
The pope, who had part of one lung removed as a young man, long battled health problems and was especially prone to respiratory illnesses in the winter.
