Francis picked up the kids, who hail from Syria, Nigeria and Congo, at the start of his weekly general audience and zoomed around St. Peter's Square with them in the backseat. Some waved, others gave a thumbs up before bidding Francis goodbye with hugs and a selfie.
The Vatican said some of the children had arrived in Italy on a migrant boat a few months ago, while others arrived April 29 with their families via a humanitarian corridor. They were being cared for by a humanitarian group in Rome.
Francis has clashed with Italy's hard-line government about the need to welcome and integrate migrants, and his gesture followed mounting tensions with right-wing politicians ahead of European Parliament elections May 26.
The latest blowup occurred when Francis' top charity aide climbed into a manhole over the weekend to restore electricity to a building full of squatters after the power company pulled the plug over unpaid bills.
Francis returned home from a 2016 trip to a Lesbos, Greece refugee camp with a dozen Syrians on his plane.
