VATICAN CITY (AP) — Pope Francis says next month he will elevate to cardinal's rank 13 churchmen, including two who have worked to help migrants.

Francis made the surprise announcement Sunday to faithful in St. Peter's Square. Several of his picks come from developing or poor countries, like Cuba, Congo and Guatemala, or places where Christians are a minority, like Indonesia. Ten of the men are under 80 and eligible to vote in any conclave to elect a new pontiff.

The ceremony to formally give the churchmen the red cardinal hat will be held on Oct. 5 at the Vatican.
