Tehran - Three sons of slain Iranian leader Ayatollah Ali Khamenei prayed beside his coffin and those of four other family members on Sunday, but Mojtaba, the son who has succeeded him as Iran’s ​supreme leader, did not make an appearance.State TV showed Mostafa, Meysam and Masoud Khamenei praying behind the ‌coffins laid ‌out in the vast courtyard of Tehran’s Imam Khomeini Grand Mosalla, a sprawling ​religious complex. In a show of public devotion to the theocratic state and revolutionary zeal, the Islamic Republic is staging a week of mass funeral processions for Khamenei, including taking his remains to Shiite religious ⁠sites in neighboring Iraq.After a day lying in state indoors for senior Iranian leaders and foreign officials to visit, Khamenei’s ⁠coffin was displayed outdoors on Saturday under glass, along with those of his daughter, son-in-law, daughter-in-law and 14-month-old granddaughter.
