Tens of thousands of mourners have attended funeral processions for Iran’s late supreme leader Ayatollah Ali Khamenei in the Iraqi cities of Najaf and Karbala, Al Jazeera reports.

Khamenei’s remains have now returned to Iran, where he will be laid to rest in Mashhad on July 9.

The 86-year-old leader was killed in a US-Israeli attack on his compound in Tehran in late February.
