Pope Francis has met with Grand Ayatollah Ali al-Sistani, one of the most senior clerics in Shi'ite Islam, in Iraq's holy city of Najaf, to deliver a message of peaceful coexistence, urging Muslims to embrace Iraq's long-beleaguered Christian minority.
The historic meeting in al-Sistani's humble home was months in the making, with every detail painstakingly discussed and negotiated between the ayatollah's office and the Vatican.
The closed-door meeting will touch on issues plaguing Iraq's Christian minority. Al-Sistani is a deeply revered figure in Shi'ite-majority Iraq and and his opinions on religious matters are sought by Shi'ites worldwide.
On the few occasions where he has made his opinion known, the notoriously reclusive al-Sistani has shifted the course of Iraq's modern history.
In the years after the 2003 US-led invasion he repeatedly preached calm and restraint as the Shi'ite majority came under attack by al-Qaeda and other Sunni extremists. The country was nevertheless plunged into years of sectarian violence.
Pope Francis arrived in Iraq on Friday and met with senior government officials on the first-ever papal visit to the country. It is also his first international trip since the start of the coronavirus pandemic.
Iraqis have welcomed the visit and the international attention it has given the country as it struggles to recover from decades of war and unrest. Iraq declared victory against the Islamic State group in 2017 but still sees sporadic attacks.
It has also seen recent rocket attacks by Iran-backed militias against US military and diplomatic facilities, followed by US airstrikes on militia targets in Iraq and neighbouring Syria.
The violence is linked to the stand-off between the US and Iran following Washington's withdrawal from the 2015 nuclear accord and its imposition of crippling sanctions on Iran.
