TEHRAN -- At least eight civilians were killed and 95 others wounded in US and Israeli attacks on a bridge in Iran's northern Alborz province on Thursday, the official news agency IRNA reported.

According to the report, the B1 bridge, located in the provincial capital Karaj, is one of the highest bridges in the Middle East and among the most complicated projects in Iran. It was targeted twice with missiles on Thursday.

IRNA cited Qodratollah Seif, the province's deputy governor for political, security and social affairs, as saying that among those killed and injured were the inhabitants of Bileqan village, passengers and the families who had gathered in the nearby areas for the Nature Day, a traditional Iranian holiday marking the end of the Nowruz holidays.

He added that there were no military activities in the areas surrounding the bridge, stressing that the structure was under construction and scheduled to be inaugurated in the coming days.

Seif said those injured in the strikes were immediately transferred to nearby medical centers, and some of them were hospitalized.

Condemning the attacks in a post on social media platform X, Iran's Foreign Minister Seyed Abbas Araghchi said, "Striking civilian structures, including unfinished bridges, will not compel Iranians to surrender."

He added, "It only conveys the defeat and moral collapse of an enemy in disarray. Every bridge and building will be built back stronger. What will never recover: damage to America's standing."

On Feb. 28, Israel and the United States launched joint attacks on Tehran and several other Iranian cities, killing Iran's then Supreme Leader Ali Khamenei, along with senior military commanders and civilians. Iran responded with waves of missile and drone strikes targeting Israel and US assets in the Middle East.
