Pope Leo XIV had a phone call with Ukrainian President Volodymyr Zelenskiy on Monday and spoke about ceasefire proposals, Zelenskiy said, in the first known conversation between the newly-elected pontiff and a foreign leader.

The pope entered the church and stopped to pray, first in front of the altar and then in front of the image of the Virgin Mary, where he recited Pope John Paul II’s prayer to the Mother of Good Counsel, according to the Vatican press room.

Pope Leo XIV stepped out onto the balcony of St. Peter’s Basilica to thunderous applause and an electric atmosphere, to deliver his first Sunday blessing and an address calling for peace in Ukraine and Gaza.
