Pope Leo has urged Ukraine and Russia to find the 'courage' to hold direct talks to end the war during his first Christmas remarks to crowds in St Peter's square.
He called for an end to conflicts around the world during his Urbi et Orbi address, which is traditionally delivered by the pontiff on Christmas Day to worshippers gathered in Vatican City.
Speaking about Ukraine, the Pope said: 'May the clamour of weapons cease, and may the parties involved, with the support and commitment of the international community, find the courage to engage in sincere, direct and respectful dialogue.'
His plea comes as US-led negotiations on a deal to end the fighting continue.
The US has sought to put together an agreement acceptable to both sides, but direct talks between Russia and Ukraine have not occurred during the latest round of diplomatic efforts.
Pope Leo also decried turmoil and conflict plaguing other parts of the world, including Thailand and Cambodia where deadly border clashes have flared up despite a ceasefire in July.
He asked that the Southeast Asian nations' 'ancient friendship' be restored and 'to work towards reconciliation and peace.
During an earlier Christmas Day sermon in St Peter's Basilica, Pope Leo lamented conditions for homeless people the world over, and the damage caused by conflicts.
'Fragile is the flesh of defenceless populations, tried by so many wars, ongoing or concluded, leaving behind rubble and open wounds,' he stated.
He emphasized the story of the birth of Jesus, illustrating that God had 'pitched his fragile tent' among the people of the world and questioned the conditions of Palestinians enduring hardship in Gaza.
The Pope's comments come amidst the backdrop of a devastating conflict in Gaza, exacerbated by severe winter storms affecting a population that is largely displaced.
