US President Donald Trump on Thursday said the tallest bridge in Iran has been destroyed and threatened more such attacks if Tehran does not make a deal to end the war "before it is too late."
Trump's comments came hours after he threatened to bomb Iran "back to the Stone Ages," as the ongoing West Asia conflict --triggered by US-Israeli strikes on Tehran-- entered the fifth week.
In a post on social media, Trump shared footage of smoke rising from the B1 bridge in Karaj, around 20 miles (35 kilometers) southwest of Tehran.
"The biggest bridge in Iran comes tumbling down, never to be used again – Much more to follow! 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 said.
Iranian state television had earlier reported two US-Israeli strikes on the bridge.
"A few minutes ago, the American-Zionist enemy once again targeted the B1 bridge in Karaj," state TV said, adding that an initial strike had caused two civilian casualties.
It said the later attack took place as emergency teams were deployed to the site to help victims of the first strike.
The B1 bridge, which was still under construction, is considered the Middle East's tallest according to Fars/Iranian media, with a 447-foot (136-meter) column.
A century-old medical research centre and steel plants in Tehran were also targeted by US-Israeli strikes on Thursday, according to Al Jazeera.
Meanwhile, Iran said it has carried out a drone attack on US fighter jets at the airbase in Al Azraq, Jordan.
The US diplomatic and logistics centre, located in the airport complex in western Baghdad, was targeted by a drone attack amid the American Embassy's warning that pro-Iran armed groups in Iraq may attack the city in the coming one or two days.
A missile was launched from Yemen towards Israel as Jerusalem reported multiple attacks from Iran on Thursday.
Meanwhile, UN chief Antonio Guterres warned that the Middle East conflict risked spiralling into a wider war, and called for an immediate halt to US-Israeli strikes on Iran and Iranian attacks on its neighbours.
"We are on the edge of a wider war that would engulf the Middle East with dramatic impacts around the globe," the secretary-general told reporters in New York.
Trump addressed his nation on Wednesday and said the war was almost over -- even as he threatened to bomb Iran "extremely hard" if it didn't bow to his demands.
"Over the next two to three weeks, we are going to bring them back to the Stone Ages, where they belong," he said in his first prime-time address to the nation on the war.
