By Yesim DikmenCASTEL GANDOLFO, Italy, April 7 (Reuters) - Pope Leo said on Tuesday that threats against the population of Iran are "unacceptable," in an unusual appeal hours after U.S. President Donald Trump said "a whole civilization will die tonight" in a social media post that shocked world leaders."Today, as we all know, there was this threat against the entire people of Iran, and this is truly unacceptable," said the pope, who has emerged as an outspoken critic of the Iran war.
