VATICAN CITY, Holy See (AFP) – Pope Francis urged peace in the Middle East at his Christmas address Sunday, in which he offered comfort to terrorism victims after a year of brutal jihadist attacks.

The 80-year-old Argentine pontiff called for guns to fall silent in Syria, saying “far too much blood has been spilled” in the nearly six-year conflict which has also contributed to mass migration and homelessness.

And despite few signs of progress, he urged Israelis and Palestinians to “have the courage and the determination to write a new page of history” in his message delivered from the balcony of Saint Peter’s Basilica.

A crowd of 40,000 gathered in the square below which, despite the sunny weather, was far from full.

In her traditional Christmas Day speech, Queen Elizabeth II spoke out about the need for unity to overcome violence in the world.

“On our own, we cannot end wars or wipe out injustice, but the cumulative impact of thousands of small acts of goodness can be bigger than we imagine,” she said in the pre-recorded televised speech.

Europe has ramped up security for the holiday just days after the truck attack that left 12 dead at a Berlin Christmas market on Monday. 

In Milan, where the suspected Berlin attacker was killed in a police shootout on Friday, there was a heavy security presence around the cathedral. The entrance has been protected by concrete barriers since the Berlin atrocity.

In France, where the killings in Germany evoked memories of the jihadist truck rampage in June that left 86 people dead in Nice, 91,000 members of the security forces have been deployed to guard public spaces including churches and markets over the weekend.

Religious ceremonies in Germany were heavy with the weight of Monday’s attack, which was claimed by the Islamic State group.

“Christmas this year carries a deep wound — we are celebrating this festival in a different way this year,” said Gebhard Fuerst, bishop of Rothenburg in the southeast.

But the country’s interior minister Thomas de Maiziere praised the public’s reaction as “brilliant”.

“I am impressed by the determination… the Germans remain unshakeable,” he told the Bild newspaper.
