The explosion happened around 2 am local time, just half an hour after US Secretary of State Mike Pompeo tweeted about new US sanctions against Iran.
Our maximum pressure campaign on the Iranian regime continues. Today, we are sanctioning nine entities for their connections to Iran’s metals sector. Iran’s leaders must stop squandering resources to support proxies abroad while Iranians suffer.
