U.S. President Donald Trump warned Friday that the U.S. military "hasn't even started destroying what's left in Iran," threatening to target bridges and electric power plants next.
The statement came hours after a double U.S.-Israeli strike destroyed Iran's tallest bridge near Tehran, killing eight people and wounding 95 others, including in a second strike that hit as emergency teams were responding to the first.
"Our Military, the greatest and most powerful (by far!) anywhere in the World, hasn't even started destroying what's left in Iran. Bridges next, then Electric Power Plants!" Trump wrote on Truth Social.
"New Regime leadership knows what has to be done, and has to be done, FAST!," he added.
U.S.-Israeli forces struck the B1 bridge in Karaj, approximately 35 kilometers southwest of Tehran, twice on Thursday. Iranian state television reported the first strike caused two civilian casualties. The second attack hit as emergency teams were deployed to help victims of the initial strike.
Ghodratollah Seif, deputy governor of Alborz province, said the death toll rose to eight with 95 others wounded after the second strike destroyed the bridge's central section.
Trump posted footage on social media showing smoke rising from the bridge.
"The biggest bridge in Iran comes tumbling down, never to be used again — Much more to follow!" he wrote.
"IT IS TIME FOR IRAN TO MAKE A DEAL BEFORE IT IS TOO LATE, AND THERE IS NOTHING LEFT OF WHAT STILL COULD BECOME A GREAT COUNTRY!," Trump noted.
Videos circulating on social media showed major parts of the nearly 1-kilometer-long structure collapsing.
Authorities described the B1 bridge as the highest in the Middle East, with a 136-meter (447-foot) column.
The bridge was still under construction and designed to ease traffic congestion between Tehran and Karaj and improve access to Iran's northern provinces, according to Iranian media.
Iranian Foreign Minister Abbas Araghchi responded on X: "Striking civilian structures, including unfinished bridges, will not compel Iranians to surrender. It only conveys the defeat and moral collapse of an enemy in disarray."
Trump's infrastructure threats followed his primetime address to the nation on Wednesday, in which he argued the war launched on Feb. 28 was nearing its end while simultaneously escalating his rhetoric.
"We're going to hit them extremely hard over the next two to three weeks. We're going to bring them back to the Stone Ages, where they belong," Trump said in his first national address on the war.
Trump has repeatedly stated that the vast majority of major military targets in Iran have already been damaged or destroyed over the past month. His latest remarks signal a shift toward civilian infrastructure, including transportation and energy.
The U.S. and Israel have maintained an air offensive on Iran since Feb. 28, killing more than 1,340 people, including then-Supreme Leader Ali Khamenei.
Iran has retaliated with drone and missile strikes targeting Israel, Jordan, Iraq and Gulf countries hosting U.S. military assets.
