The son of the U.S. Marine photographer who filmed a boy carrying his dead brother in the aftermath of the atomic bombing of Nagasaki has shaken hands with Pope Francis.
Francis visited the Nagasaki ground zero Sunday and demanded world leaders renounce atomic weapons and the Cold War-era doctrine of deterrence.
Tyge O'Donnel, the son of Joseph O'Donnell, was invited to the event as a guest. His father's iconic photo was printed on cards that Francis delivered in 2017 in his anti-nuclear message.
O'Donnell, his camera hanging from the neck, approached Francis as the pope was greeting people after the speech. O'Donnell described the encounter as a "phenomenal experience."
He says the pope's eyes were "very very kind and he was well spoken. I was just amazed. I am very pleased to have met him."

Pope Francis is celebrating Mass in Nagasaki before an estimated 35,000 people — and the remains of a wooden statue of the Virgin Mary rescued from a cathedral destroyed in the 1945 atomic bomb.
The statue, which was remarkably well preserved despite the blast, was featured on the altar during Francis' Mass on Sunday.
In his homily, Francis recalled both the victims of the atomic bombing, and the thousands of Christians killed for their faith during two centuries of persecution.
He says: "We want to follow in their path, to walk in their footsteps and to profess courageously that the love poured out in sacrifice for us by Christ crucified is capable of overcoming all manner of hatred, selfishness, mockery and evasion."

Nagasaki Mayor Tomihisa Taue says Pope Francis' visit and condemnation of nuclear weapons at the site of the atomic bombing that devastated the Japanese city at the end of World War II is a powerful message.
Francis arrived first in Nagasaki on Sunday to pray for the victims of the American bombing, three days after the first A-bomb hit Hiroshima, where he is also visiting later Sunday.
Francis demanded world leaders renounce atomic weapons and the Cold War-era doctrine of deterrence.
Taue says the pope delivered a message that "reminded us of the most important and basic concept to achieve a world without nuclear weapons."
The atomic bomb attack on Nagasaki on Aug. 9, 1945, killed 74,000 people. The earlier bombing of Hiroshima killed 140,000.

Is the pope "Kyoko," or "Ho-o" in Japanese?
The Japanese government adopted the term "Kyoko" as the official translation of his title ahead of his visit this weekend, in line with the policy of the Catholic Church in Japan.
Catholics also used both titles but adopted the new title "Kyoko" following the 1981 visit to Japan by St. John Paul II. The faithful say it includes the Chinese character that clearly shows that the pope is a man of teachings. The Chinese characters used in the new title literally mean "emperor of teachings." The earlier one meant "king of law."
The official translation of the pope had been "Ho-o" in Japanese dating from when the Vatican established ties with Japan in 1942. That name remains on a plate posted at the Vatican's embassy entrance.
Many Catholics actually call the pope "Kyoko-sama," or "Kyoko-san." Phonetically, "Kyoko" is also a common name for Japanese women.
10:10 a.m.
Pope Francis is bringing his peace message to Nagasaki and Hiroshima on his first full day in Japan, paying homage to the victims of the U.S. atomic bombings and demanding an end to the stockpiling and use of nuclear weapons.
Francis was arriving first in Nagasaki as a downpour Sunday drenched the terraced fields and rice paddies around town, where autumn has begun turning hills of green into shades of red, yellow and orange.
Japanese Catholics and others are braving the rain in plastic raincoats, some queuing up for hours to secure a spot for Francis' Mass in the baseball stadium. Others gathered at the outdoor memorial to bombing victims at ground zero, where Francis was expected to deliver a strong appeal for complete nuclear disarmament.
