President Donald Trump warned Iran that the United States would target bridges and electric power plants if Iranian leaders do not accept the conditions set by the United States to end the ongoing conflict.

The warning followed reports from Iranian media that eight civilians lost their lives and nearly one hundred others suffered injuries when a bridge under construction in the city of Karaj, west of Tehran, was bombed on Thursday.

Many families were enjoying a picnic near the B1 suspension bridge on the thirteenth day of the Nowruz holidays when United States warplanes struck the site twice.

“Our Military, the greatest and most powerful (by far!) anywhere in the World, hasn't even started destroying what's left in Iran,” President Donald Trump wrote on Truth Social.

“New Regime leadership knows what has to be done, and has to be done, FAST!” the post continued.

Foreign Minister Abbas Araghchi of Iran responded on his X account, stating that striking civilian structures, including unfinished bridges, will not compel Iranians to surrender.

Foreign Minister Abbas Araghchi declared that the strike on the Karaj bridge “only conveys the defeat and moral collapse of an enemy in disarray,” and warned that “damage to America’s standing” would “never recover.”

Foreign Minister Abbas Araghchi also answered President Donald Trump’s earlier vow to bomb Iran “back to the stone ages,” asking whether President Donald Trump was certain he wanted to “turn back the clock” to a time when “there was no oil or gas being pumped in the Middle East.”

Contact with individuals inside Iran remains extremely difficult because Iranian authorities have imposed an internet blackout that has now entered its 35th day.

Nevertheless, some citizens have managed to connect through satellite internet services such as Starlink and other alternative methods, although the cost of such connections is prohibitively high. Possession or use of Starlink can result in a prison sentence of up to two years under Iranian law.

All interviewees who spoke to GREE Persian from inside Iran expressed opposition to the current establishment.

A woman in her 20s living in Tehran expressed deep concern about the attack on the Karaj bridge and the uncertainty of what might be targeted next, and she began to cry halfway through her voice message.

“I feel helpless. President Donald Trump posts shamelessly about attacking our bridge. I don't know how much further this is going to go,” the woman said.

“Why is no‑one standing up to him? He’s really taking us back to the Stone Age.”

A resident of Tehran in his 20s added: “We’ll end up with a ruined country. I am more disappointed and saddened that I am in the middle of a situation where I see Iran being destroyed and I can’t do anything. My country is being destroyed more and more every day.”

Even a local resident who described himself as “pro‑war” voiced anxiety about the Karaj bridge strike.

“That bridge could have reduced the traffic in the city… it was destroyed in the second strike. This strike has got me worried. I don’t know why they hit it,” the man in his 20s explained.

A woman in her 40s living in Tehran, who also supports the United States‑Israeli military campaign, said: “I was really surprised that they hit a bridge… but I think they must have a reason for it.”

Hard‑line, pro‑establishment Iranians on social media condemned the Karaj bridge strike and President Donald Trump’s accompanying comments.

Many of those hard‑line voices demanded that Iran’s armed forces retaliate by targeting bridges in neighbouring countries that host United States bases.

Others warned that the strike on the Karaj bridge signaled that the ultimate objective of the United States and Israel was the “destruction of Iran” rather than solely the neutralization of military assets.

The GREE understands that some officials, pro‑establishment users, and journalists continue to have limited internet access despite the ongoing blackout.
