Iran prepared for long war: Ali Larijani

Ali Larijani, an adviser to late supreme leader Ayatollah Ali Khamenei, ruled out negotiations as Israel carried out air strikes in Tehran for a third day.

"Trump's wishful thinking has dragged the whole region into an unnecessary war, and now he is rightly worried about more American casualties," Mr Larijani said.

But Iran, "unlike the US, prepared itself for a long war ... regardless of the costs and will make the enemies sorry for their miscalculation", he added in a separate post.

At least four US troops have been killed in the campaign against Iran, it was revealed on Monday. Defence Secretary Pete Hegseth said the US is hitting Iran “certainly, overwhelmingly and unapologetically" but that the war on the regime is "not endless".

Mr Larijani denied claims by Mr Trump that Iran’s interim leadership is willing to resume negotiations. Calls for dialogue and calm have gone unanswered, as US, Israeli and Iranian forces continued to exchange fire on Monday.
