Pope Francis has attacked what he called “the atmosphere of war,” which he believes is hampering the world. He also attacked those profiteering from war and those engaging in arms sales, as he led a mass in Bosnia on Saturday.

Francis received a joyous welcome from around 100,000 people who lined the streets of Sarajevo, Bosnia’s capital, as his motorcade made its way to the national stadium, where the pontiff celebrated mass for a mainly Catholic audience of around 65,000, speaking in Italian.
