Pope Leo says he has "no intention to debate" US President Donald Trump, after the US leader criticised the pontiff's comments about the war in the Middle East.

"I am not a politician," Pope Leo tells reporters, while defending his earlier remarks. "The message is the same: to promote peace."

On Saturday - as Iranian and American negotiators met in Pakistan for talks to end the war - Pope Leo urged the international community to end "the madness of war". He also denounced the use of Christian language to justify war.
