FIFTY people have been killed and more than 200 injured in a stampede as Iranians gathered for the burial of a leading commander killed in a US drone strike, BBC has quoted Iranian media report.
The deaths led to the postponement of Qasem Soleimani's interment. A new time will be announced later, officials say.
Soleimani is being laid to rest in his hometown of Kerman, 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 Ali Khamenei.
The US saw him as a terrorist and a threat to American troops.
US President Donald 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.
According to BBC, it is unclear what caused the stampede in Kerman, south-eastern Iran, but vast numbers of people were in the streets ahead of Soleimani's burial, first set for Tuesday morning.
The exact death toll is unconfirmed - one emergency official put it at 32 while another said it was 40.
Nearly 200 people are also said to have been injured, the BBC website has reported.
