Millions of mourners have gathered at the Grand Mosalla in Tehran for the funeral prayers of Iran's Supreme Leader, Ayatollah Ali Khamenei. By Sunday morning, the venue had reached full capacity before the prayers began, prompting authorities to close all entrances to the prayer grounds.

According to Iranian state media, funeral prayers are also being held for four members of Khamenei's family. Large numbers of people from across the country have traveled to Tehran to pay their final respects.

The funeral prayers will be led by Ayatollah Sheikh Jafar Sobhani. In the days leading up to the funeral, memorial ceremonies and tribute events were held in cities across Iran.

The funeral in Tehran is being regarded as the largest event of the country's national mourning ceremonies.
