The King's Christmas message has emphasised the importance of "universal" values shared between major religions, at a time of "increasingly tragic conflict around the world".
Axar.az reports that against a backdrop of conflicts in Israel, Gaza and Ukraine, he pointed to Jesus's words: "Do to others as you would have them do to you."
King Charles also talked of protecting the planet as being a spiritual duty.
And he praised the efforts of volunteers helping those in need.
The King's second Christmas broadcast, recorded in Buckingham Palace, wove together some of his most personal causes - building bridges between faiths, protecting the environment and caring for the most vulnerable.
He has long campaigned for supporting links between different religious communities, at home and abroad, and a major theme of this year's message is how much the major religions have in common, despite the violence raging in the Middle East and elsewhere.
