Iran’s leadership has also warned neighbouring states that host US military bases.
Iranian President Masoud Pezeshkian said Iran would be forced to respond if any country allowed its territory to be used as a launch point for attacks against Iran.
However, he said such a response would not mean Iran had a dispute with the people of those countries.
Instead, he described it as a necessary reaction to defend Iran’s territory.
On Saturday, the Iranian president apologised to neighbouring countries whose territories had been affected by attacks.
Iranian leaders say the US is ‘trapped’
Iranian officials have also criticised the United States. Iran’s security chief Ali Larijani said the Trump administration expected a quick victory similar to the political situation in Venezuela, where the US tried to remove President Nicolás Maduro.
According to Larijani, Washington believed it could strike Iran, take control quickly and end the conflict.
But he said the situation has instead turned into a difficult and dangerous conflict.
“They thought it would be like Venezuela… but now they are trapped,” he said during an interview broadcast on Iranian state television.
Growing fear among civilians in Iran
Inside Iran, civilians are increasingly worried about the impact of the war.
Damage to residential areas and infrastructure has been reported in several cities.
Security forces are also highly visible on the streets.
A 26-year-old teacher told AFP that the fear of war is difficult to describe for people who have never experienced it.
“I don’t think anyone who hasn’t experienced war would understand it,” the teacher said.
According to Iran’s health ministry, at least 926 civilians have been killed and around 6,000 people injured so far.
However, these figures have not been independently verified.
