Images of Pope Francis’ body in a velvet-lined wooden casket have been released by the Vatican as throngs of supporters flock to pay their respects to the late pontiff. The 88-year-old died on Easter Monday of a heart attack following a stroke.

Heads of state are expected for Francis’ funeral, but the three days of public viewing in the basilica allow ordinary Catholics to grieve the Argentine pope. The viewing ends Friday at 7 p.m., after which Francis’ casket will be closed and sealed.
