Ayatollah Ali Khamenei’s body was brought to Najaf, Iraq, where millions of mourners gathered for a funeral procession on Tuesday night. The procession began at the Al-Kufa Bridge and moved toward the shrine of Imam Ali, one of the holiest sites for Shia Muslims. Video footage showed Najaf transformed into a sea of people as Khamenei’s coffin and family members arrived by plane.

Following several days of memorial events in Iran, the funeral ceremonies were transferred to Iraq. Officials confirmed that Khamenei’s body will also be taken to Karbala, where additional processions are planned. Experienced Iraqi officials and volunteers have been preparing for the upcoming ceremonies in Karbala.

Khamenei, the leader of the Islamic Revolution, was killed on February 28 in a U.S.-Israeli attack along with members of his family and senior officials, according to the report.
