Iran began six days of public funeral ceremonies for Khamenei on Saturday, including a dedicated day to neighbouring Iraq, a Shia powerhouse with close ties to Tehran.The Islamic republic hopes the marathon ceremonies will project strength and unity after the Middle East war, which started with US-Israeli strikes that killed Khamenei and several relatives on February 28.After a massive procession in Iran's holy city of Qom, Iraqi officials and senior politicians received the remains of Khamenei on Tuesday night at Najaf international airport in the presence of Iranian President Masoud Pezeshkian.
