Francis says he is particularly concerned about children "trapped under the cruel bombardments," which yesterday left at least 25 people dead, five of them children.
During his general audience today, Francis says it's "with a sense of urgency that I renew my appeal: I'm begging with all my strength for those responsible to undertake an immediate cease-fire that is respected at least to give time to evacuate civilians."
The UN Security Council is deadlocked over how to respond to the Aleppo crisis, with Russia and the US failing to agree on renewing a cease-fire.
