Ayatollah Ali Khamenei's body will be on public display before his funeral. TEHRAN: Giant portraits of Ayatollah Ali Khamenei, Iran's late supreme leader killed in US-Israeli airstrikes , hung from Tehran's Grand Mosalla on Tuesday (Jun 30) as workers raced to prepare for his grand funeral ceremony. His funeral, initially delayed at the height of the Middle East war, will take place as Iran and the United States uphold a fragile ceasefire after signing a preliminary deal to halt the conflict.
