Iran's late president Raisi to be buried in home city of Mashhad

Ebrahim Raisi, the late Iranian president who died in a helicopter crash at the weekend, is to be buried in his home city of Mashhad on Thursday as mass mourning ceremonies continue in the country.

Raisi is to be laid to rest at the city's shrine of Imam Reza, the eighth imam of Shia Islam.

High-ranking representatives of friendly states are expected to attend, including Russian parliamentary leader Vyacheslav Volodin. Iran's state railway company organized special trains to take mourners from Tehran to the north-eastern city.

Before arriving in Mashhad, there was a state-organized service on Thursday morning in the city of Birjand in which tens of thousands of people turned out, state broadcaster IRIB said.

Raisi represented Birjand, located south of Mashhad, on the Assembly of Experts, an influential clerical body in Iran.

There have been several ceremonies and public displays of mourning for Raisi, late foreign minister Hossein Amirabdollahian and other victims of Sunday's crash, with millions of mourners flocking to a funeral procession in Tehran on Wednesday.

Amirabdollahian's funeral took place on Thursday in Tehran. The Iranian state news agency ISNA said the burial was held in the Shah Abdol-Azim Shrine in the south of the capital.

Raisi and Amirabdollahian were killed in the crash with seven other occupants of the ill-fated helicopter. They went down in dense fog in the mountains while travelling back from a meeting with Ilham Aliyev, the president of neighbouring Azerbaijan.

Iranian Supreme Leader Ayatollah Ali Khamenei ordered five days of national mourning, and a nationwide holiday was held on Wednesday.

Raisi's death has provoked mixed reactions in Iran. While supporters of the country's Islamic regime have mourned the loss of an important political figure, critics have highlighted the heightened repression his administration oversaw.
