Pope attacks abortion in his message for Christmas
Pope Francis used his Christmas message to urge Catholics around the world to feel compassion for those "not allowed to be born".
Speaking to tens of thousands of Catholics in Saint Peter's Square, the head of the Catholic Church asked worshippers to celebrate "the fragile simplicity of a small newborn".
"Let us allow ourselves to be challenged by the children who are not allowed to be born, by those who cry because no one satiates their hunger, by those who do have not toys in their hands, but rather weapons," he said.
During his speech to 1.2 billion Catholics around the world, the Pontiff also wished Christmas peace for people scarred by wars and those who lost loved ones to terrorism.
He said terrorism was sowing "fear and death" in many cities and countries.
Some 40,000 tourists and Romans calmly endured long security queues to enter St Peter's Square to see the Pope on the central balcony of St. Peter's Basilica, where he delivered the traditional Urbi Et Orbi (to the city and to the world) Christmas message and blessing.
Francis spoke sorrowfully of the suffering caused by the Syrian war, especially in Aleppo, pressing the international community to help negotiate a solution.
He urged Israelis and Palestinians to "write a new page of history, where hate and revenge give way" toward building a future of understanding and harmony.
He also cited the "brutality of terrorism" in Iraq, Libya and Yemen.
In Nigeria, the Pope lamented, "fundamentalist terrorism exploits even children", a reference to child suicide bombers. He expressed hope that dialogue would prevail over "the mindset of conflict" in both South Sudan and the Democratic Republic of the Congo.
The heavy security at the Vatican reflected apprehension in much of Europe, which is reeling from extremist attacks.
Last week, 12 people died in Berlin when a Tunisian man who had pledged allegiance to Isil ploughed a lorry through a crowd at a Christmas market. He was killed a few days later in a shoot-out near Milan.
"Peace to all those who have been injured or have suffered the loss of a loved one due to the brutal acts of terrorism that have sown fear and death in the heart of many countries and cities," the Pope said.
Referring to the meaning of Jesus' birth, Francis said: "Today this message goes out to the ends of the Earth to reach all peoples, especially those scarred by war and harsh conflicts that seem stronger than the yearning for peace."
His Christmas message also recalled Colombia, which has seen his personal intervention try to end Latin America's longest-running conflict, and Venezuela, where a papal envoy has tried to facilitate talks between the government and the opposition as Venezuelans endure widespread food and medicine shortages.
Francis expressed concern over tensions on the Korean peninsula, and over Burma, which he said should "consolidate efforts to promote peaceful coexistence".
Throughout his papacy, Francis has denounced the Islamic extremist violence that has driven Christians from communities that date to Christianity's foundations.
He has also demanded that Europe, in particular, do more to welcome refugees.
