Pope Francis to meet Iraq's top Shia cleric on March visit 29.01.2021 Pope Francis is set for an historic meeting with Iraq's top Shia Muslim cleric, Grand Ayatollah Ali al-Sistani, during a trip to Iraq planned for March, the patriarch of Iraq's Chaldean Catholic Church said on Thursday. The visit, which eluded Francis's predecessors, takes place amid deteriorating security in some parts of Iraq and after the first big suicide bombing in Baghdad for three years. The programme for the March 5-8 trip, announced at a news conference by Patriarch Louis Raphael Sako, who is a Catholic cardinal and head of Iraq's biggest Christian denomination, will include Masses in Baghdad and the northern city of Erbil.
