The Iranian authorities held a funeral service on Tuesday for the late President Ebrahim Raisi and Foreign Minister Hossein Amirabdollahian. Both men were killed in a helicopter crash in a mountainous part of the country's north-west region over the weekend. Iranian state broadcaster IRIB showed scores of mourners who gathered in Tabriz to pay their respects at the procession. Iran's government has blamed bad weather and dense fog for the accident.
