Where was Ayatollah Khamenei's body till now & why is his funeral being held after 4 months?

Iran's former Supreme Leader Ayatollah Ali Khamenei's burial is being held over four months after he died in US and Israeli strikes. Iranian officials have insisted the delay was due to severe, volatile conditions of the active war. Counterterrorism expert Dr Mohammed Omar said Ayatollah's remains were "almost certainly refrigerated cold storage, not embalming, as Islam bars chemical embalming."
