Pope, young people chant against corruption in DRC

STORY: Addressing more than 65,000 young people in Martyrs Stadium, Francis led the stadium in an impromptu chant of "no to corruption" in French, Congo's lingua franca.

"No to corruption! No to corruption! All say it, no to corruption," the pontiff said, to which the crowd responded with loud applause and cheers.

Congo has some of the world's richest deposits of diamonds, gold, copper, cobalt, tin, tantalum and lithium, but its abundant mineral resources have stoked conflict between ethnic groups, militias, government troops and foreign invaders.
