Pope Leo blasted leaders ​who spend billions on ‌wars and said the world was "being ravaged by ​a handful of ​tyrants", in unusually forceful remarks ⁠in Cameroon on ​Thursday after U.S. President ​Donald Trump attacked him again on social media.

Leo, the first ​U.S. pope, also ​decried leaders who used religious ‌language ⁠to justify wars and urged a "decisive change of course" in a ​meeting in ​the ⁠biggest city in Cameroon's English-speaking ​regions, where a simmering ​conflict ⁠going back nearly a decade has left ⁠thousands ​dead.
