Pope Francis has criticised the naming of the US military's largest non‑nuclear explosive ever used in combat as "the mother of all bombs".
Pope Francis says he was ashamed when he heard the name.
He says a mother gives life and this one gives death, and we call this device a mother.
Last month the US dropped such a bomb, which weighs 9,800kg, on Islamic State militants in Afghanistan.
The Pentagon said it was dropped from a US aircraft in Nangarhar province, targeting tunnel complex used by IS.
The Pope's comments come ahead of his meeting with US President Donald Trump on 25th May.
