Dozens of mourners have reportedly been killed after a stampede erupted during a funeral procession for top Iranian military commander Qassem Soleimani, who was killed in a U.S. airstrike last week. Iranian state TV reported the incident happened in Soleimani’s hometown of Kerman, in southeast Iran, and has left at least 40 people dead and 213 others injured. The disaster has forced the delay of Soleimani’s burial, according to the semi-official ISNA news agency, which was quoted by Reuters. The report did not say how long the delay of the burial would last. Videos of the incident showed people lying motionless on a road while others shouted and tried to help them. There have been widespread commemorations in Iran since Soleimani’s assassination—a procession in Tehran on Monday drew over a million people in the Iranian capital.
