The US president has released footage of the Iranian bridge strike.
Donald Trump has called on Iran to reach a deal before it is too late.
"The largest bridge in Iran is collapsing, and it will never be used again - many more things will follow! It is time for Iran to reach an agreement before it is too late, and there is nothing left of what could have been a great country!" he said.
According to Fars News Agency, the B1 bridge between Tehran and Karaj, which is 136 meters high, is considered the highest bridge in the Middle East and was inaugurated earlier this year.
State media described it as "one of the most complex engineering projects in West Asia."
Otherwise, the bridge was reportedly valued at around $400 million (346 million euros). /Telegraph/
