The IDF’s Persian-language spokesperson released an unusual public warning Tuesday morning, directly addressing civilians across Iran and urging them to avoid train travel nationwide.

In the announcement, the IDF called on the Iranian public not to use trains or travel near railway lines anywhere in the country for a limited period.

According to the statement, the advisory remains in effect until 9:00 p.m. local time in Iran. The IDF emphasized that the purpose of the warning is to protect civilian lives, stating: “Your presence on trains and near railway lines endangers your life.”

The warning was issued on the same morning that President Donald Trump had previously referred to as “Power Plant Day, and Bridge Day,” in which he warned that if Iran failed to reopen the Strait of Hormuz by 8:00 p.m. EST Tuesday, the United States and Israel would target key infrastructure, including civilian facilities.
