Iran has officially begun six days of public funeral ceremonies for late supreme leader Ayatollah Ali Khamenei, state television reports, with processions due to continue in Iraq before his burial, according to AFP.

Thousands of mourners carrying red banners, a symbol associated with calls for revenge, gathered in the courtyard of Tehran's Grand Mosalla ahead of the arrival of Khamenei's coffin, chanting "death to America" and "revenge, revenge".

Iranian authorities say they anticipate between 15 and 20 million participants in Tehran alone over the next three days for tributes to the man who ran the country for three-and-a-half decades.

Six days of funeral ceremonies are planned to commemorate Khamenei, who ruled the Islamic republic as its number one from 1989 until his killing aged 86 on the first day of the US-Israeli war with Iran on February 28.

It is a long established fact that a reader will be distracted by the readable content of a page when looking at its layout. The point of using Lorem Ipsum is that it has a more-or-less normal distribution of letters, as opposed to using 'Content here, content here', making it look like readable English. Many desktop publishing packages and web page editors now use Lorem Ipsum as their default model text, and a search for 'lorem ipsum' will uncover many web sites still in their infancy. Various versions have evolved over the years, sometimes by accident, sometimes on purpose (injected humour and the like).
