Pope Francis has presided over the Vatican's sombre Easter Vigil service, a day after making the last-minute decision to skip his participation in the Good Friday procession at the Colosseum as a health precaution.
Francis entered the darkened, silent St Peter's Basilica in his wheelchair, took his place in a chair and offered an opening prayer.
Sounding somewhat congested and out of breath, he blessed an elaborately decorated Easter candle, the flame of which was then shared with other candles until the whole basilica twinkled.
The evening service, one of the most solemn and important moments in the Catholic liturgical calendar, commemorates the resurrection of Jesus and includes the sacrament of baptism for eight adult converts.
The Vatican had said to ensure his participation in both the vigil service Saturday night, which usually lasts about two hours, and Easter Sunday Mass a few hours later.
The 87-year-old, who had part of one lung removed as a young man, has been battling respiratory problems all winter that have made it difficult for him to speak at length.
He and the Vatican have said he has had bronchitis, a cold or the flu.
He has cancelled some audiences and often asked an aide to read aloud some of his speeches.

The Vatican said in a brief explanation that the decision was made to "conserve his health".
While Francis also skipped the chilly Good Friday procession last year because he was recovering from bronchitis, his sudden absence from the event this year underscored how his frail health was affecting even major liturgical events at the Vatican.
