ISTANBUL

China on Friday reiterated its opposition to attacks on civilian infrastructure after the US targeted what officials described as Iran’s “biggest bridge,” urging all parties to immediately ceasefire.

Responding to a media question about a social media video released by US President Donald Trump showing the strike, Foreign Ministry spokesperson Mao Ning called on all sides to return to political and diplomatic solutions and prevent a wider humanitarian disaster, according to Chinese state-run Global Times.

“The military actions taken by the United States and Israel against Iran were conducted without authorization by the UN Security Council and are in clear violation of international law,” she said.

On Thursday, Trump said the biggest bridge in Iran “comes tumbling down and never to be used again” and warned that "Much more to follow."

A US-Israeli strike hit a key bridge on a major highway in northern Iran earlier Thursday. According to Fars News Agency, multiple sites were struck in the Azimieh area near the city of Karaj, including the B1 Bridge, described as the highest bridge in the Middle East.

The outlet reported several injuries and said the bridge, part of a major infrastructure project expected to be inaugurated soon, was damaged.

Reports indicated the US military may have carried out a so-called “double tap” strike, meaning the same location was hit twice in succession.

The region has been on alert since the US and Israel launched an air offensive on Iran on Feb. 28, killing more than 1,340 people so far, including then-Supreme Leader Ali Khamenei.

Iran has retaliated with drone and missile strikes targeting Israel as well as Jordan, Iraq and Gulf countries hosting US military assets, causing casualties and infrastructure damage while disrupting global markets and aviation.
