At least 30 people have been killed in a stampede as Iranians gathered for the burial of a top commander killed in a US drone strike, Iranian media report.
More than 40 others were injured in the incident in Kerman, according to the reports.
Qasem Soleimani is being laid to rest in his hometown with millions already estimated to have packed the streets for funeral processions.
His killing has raised fears of a conflict between the US and Iran.
Soleimani was widely considered the second most powerful man in Iran behind Supreme Leader Khamenei. The US saw him as a terrorist and a threat to American troops.
President Trump adopted a tough stance against Iran after his election and Tehran responded with their own campaign. Tensions were raised further last month after the US attacked an Iranian-backed militia in Iraq it blamed for attacks on US forces.
