Dubaiinfo-icon- The Israeli military warned Iranians in Farsi on Tuesday to avoid taking trains until at least 9 pm local time, likely signalling a new target for its airstrikes.

The warning came in a post on X.

"Your presence puts your life at risk," the warning read.

USinfo-icon President Donald Trumpinfo-icon earlier demanded that Iraninfo-icon open the Strait of Hormuzinfo-icon or see power plants and bridges wiped out. The threat to hit civilian infrastructure has sparked widespread warnings about possible warinfo-icon crimes.

New Zealandinfo-icon Prime Minister Christopher Luxon on Tuesday urged Trumpinfo-icon not to follow through, saying the "focus needs to be on not seeing this conflictinfo-icon expand any further."

"Any of those actions, including bombing bridges and reservoirs and civilian infrastructure, would be unacceptable," Luxon told Radioinfo-icon New Zealand.

Reports from Iran say people are forming human chains around power plants ahead of the threatened strikes.

"Power plants that are our national assets and capital, regardless of any taste or political viewpoint, belong to the future of Iran and to the Iranian youth," said Alireza Rahimi, secretary of the Supreme Council of Youth, in a video call in a newscast.

Iran has formed human chains in the past around its nuclear sites at times of heightened tensions with the West.

UN Secretary-General Antonio Guterres warned the US that attacks on civilian infrastructure are banned under international law, according to his spokesperson.

Trump, speaking with reporters, said he's "not at all" concerned about committing war crimes with such attacks.
