Pope Francis is flying to Iraq for the first ever papal visit to the country, and his first international trip since the start of the pandemic.
The four-day trip is meant to reassure Iraq's dwindling Christian community and foster inter-religious dialogue.
The Pope will meet Iraq's most revered Shia Muslim cleric, say a prayer in Mosul and celebrate Mass at a stadium.
He has insisted on travelling despite a new spike in Covid-19 infections in Iraq and concerns over his security.
About 10,000 Iraqi Security Forces personnel will be deployed to protect the Pope, while round-the-clock curfews are also being imposed to limit the spread of the coronavirus.
