JERUSALEM (REUTERS) - Pope Francis navigated the minefield of the Israeli-Palestinian conflict and humbly bowed to kiss the hands of Holocaust survivors on Monday, the last day of a Mideast trip laden with bold personal gestures.
"Never again, Lord. Never again!" he said in the dimly lit Hall of Remembrance in the Yad Vashem Museum which commemorates six million Jews killed by the Nazis in World War Two.
The fourth pope to visit Israel, he had earlier became the first to lay a wreath at the tomb of Theodor Herzl, seen as the founder of modern Zionism that led to Israel's foundation.
At the request of Prime Minister Benjamin Netanyahu, he also made an unannounced stop at Israel's "Memorial to the Victims of Terror", the day after unexpectedly praying at a towering Israeli security wall that is despised by Palestinians.
In a mirror image of the halt at the graffiti-smeared wall, Pope Francis put both hands on the neat stone and marble monument and bowed his head - an image that pleased his Israeli hosts who had smarted in silence over Sunday's impromptu stop.
"I pray for all the victims of terrorism. Please, no more terrorism," the softly spoken pope said at the memorial, which is engraved with the names of Israeli civilians killed mainly in attacks by Palestinian militants.
Mr Netanyahu, standing at his side, thanked him for his words. "We don't teach our children to plant bombs. We teach them peace, but we have to build a wall for those who teach the other side," he said, accusing Palestinian leaders of incitement.
Israel says its barrier in the occupied West Bank was erected to safeguard national security after a wave of Palestinian suicide bombings a decade ago. Palestinians see it as a brutal attempt to grab land they seek for a future state.
HUMBLE TRIBUTE TO HOLOCAUST VICTIMS
A day packed with political and religious encounters began at the gold-topped Dome of the Rock, the pope taking off his shoes before walking into the Jerusalem shrine from which Muslims believe the Prophet Mohammed climbed to heaven.
Pope Francis then went to pray at the adjacent Western Wall, one the Jews' most revered shrines and a sole remnant of their sacred Second Temple, destroyed by the Romans in 70 AD.
There, he, a rabbi, and an Islamic leader - both friends from his native Argentina he invited to make the trip with him - embraced in a sign of the inter-religious dialogue that Francis is convinced can be a catalyst for peace in the region.
At Yad Vashem, the pope made the type of gesture of humility that has become his custom since being elected pontiff in 2013.
As he was introduced to six survivors of Nazi concentration camps and told of their stories of struggle and near-starvation, he bent slowly to kiss the hand of each elderly person.
Reading a haunting personal reflection that was a cross between a poem and a prayer, he called the Holocaust "a boundless tragedy", adding: "A great evil has befallen us, such as never happened under the heavens. Now, Lord, hear our prayer, hear our plea, save us in your mercy. Save us from this horror."
The pope made one of his boldest political gestures on Sunday when he unexpectedly intervened in flailing diplomatic efforts to end the Israeli-Palestinian conflict, inviting the presidents from the two sides to his Vatican residence to pray for peace.
The meeting is expected to take place on June 6.
Both Mr Mahmoud Abbas and Mr Shimon Peres, who plays no decision-making role in Israeli diplomacy and leaves office in July, accepted the offer, which came just a month after US-led peace talks collapsed amid bitter, mutual recrimination.
"We will work together, Jews, Christians and Muslims to bring an end to the conflicts," Mr Peres said on Monday, speaking alongside the pope, a choir of children standing behind them.
However, there was little hope that the unusual prayer initiative could break decades of mutual mistrust and deadlock or resolve any of the fraught issues that have frustrated generations of diplomats and negotiators.
