The Pope has urged all parties involved in Russia's war on Ukraine to hasten an end to the conflict.
As part of his Angelus prayer, he emphasised that ongoing Russian attacks have left civilians exposed to the harsh cold of winter,
"The protracted hostilities ... have increasingly serious implications for civilians," Pope Leo said.
"I urge everyone to intensify their efforts to end this war."
It comes as the first trilateral peace talks between Russia, Ukraine and the US have ended, with no apparent breakthrough.
The two-day talks held in Abu Dhabi finished whilst heavy fighting continues.
Ukrainian officials reported that recent air strikes targeted the country’s energy infrastructure, killing one person and injuring at least 35 others.
Meanwhile, Russia has accused Ukraine of attacking an ambulance in Russian-controlled territory, resulting in the deaths of three medics, and later reported a Ukrainian missile strike on energy facilities in Belgorod.
President Volodymyr Zelensky has suggested a second round of talks could be held as early as next week, while an American official said discussions are set to resume on 1st February.
