Pope Francis, 88, died weeks after he was discharged from the hospital following a lengthy battle with double pneumonia and other health issues.

Pope Francis passed away at 88 due to complications from bilateral pneumonia, a severe lung infection affecting both lungs. It has put a spotlight on an illness that often goes unnoticed until it becomes severe.

The Philippines began a period of national mourning for Pope Francis on Wednesday, with President Ferdinand Marcos Jr ordering flags on all state buildings across the staunchly Roman Catholic country to fly at half-mast to honour the pontiff.
