TEHRAN, Iran (AP) – A stampede at a funeral for a top Iranian general slain in a U.S. airstrike has killed 56 people and injured 213 others.

Iranian state TV gave the updated death toll in the stampede in Kerman, the hometown of Revolutionary Guard Gen. Qassem Soleimani, as the procession got underway. There was no information as to what caused it. Online videos showed people lying lifeless on a road and others shouting and trying to help them.

Soleimani’s burial was delayed, with no new time set for it. Soleimani’s death has sparked calls across Iran to take revenge against America, drastically raising tensions across the Middle East.

Also on Tuesday, the U.S. warned ships across Mideast waterways crucial to global energy supplies there’s the “possibility of Iranian action against U.S. maritime interests” in the region. The U.S. Maritime Administration cited rising threats after an American drone strike in Baghdad killed Soleimani.
