Thousands marched in Iran on Thursday on the final day of funeral rites for President Ebrahim Raisi, who will be laid to rest in his hometown days after dying in a helicopter crash, reports BSS.

Raisi, 63, died on Sunday alongside his foreign minister and six others when their helicopter crashed in the country's mountainous northwest while returning from a dam inauguration.

His final resting place will be at the holy shrine of Imam Reza, a key Shiite mausoleum in the northeastern city of Mashhad, where the ultra-conservative president was born.

Images published by Iranian media on Wednesday showed officials in Mashhad preparing for the final day of funerary rites.

Large photos of Raisi, black flags and Shiite symbols were erected throughout the streets of Iran's second city, particularly around the Imam Reza shrine.

Massive crowds had gathered for a funeral procession on Wednesday in the capital Tehran to pay their final respects to the president, whom officials and media dubbed a "martyr".

Supreme leader Ayatollah Ali Khamenei -- whom Raisi had been widely expected to succeed -- led prayers for the late president, kneeling before the coffins of the eight people killed in the crash.

Among them was foreign minister Hossein Amir-Abdollahian, who will also be buried Thursday in the shrine of Shah Abdol-Azim in the town of Shahr-Rey south of the capital.

Iranian officials and foreign dignitaries paid their respects to the late top diplomat at a ceremony in Tehran ahead of the burial.
