The United States had crossed one of Iran’s most serious red lines by attacking its nuclear facilities, Iranian Foreign Minister Abbas Araghchi said Sunday.
"The US crossed a very big red line by attacking Iran’s nuclear facilities," he said.
Speaking in Istanbul, Araghchi said the US bore full responsibility for the consequences of its actions and said Tehran would respond using all tools at its disposal.
“The attack on peaceful nuclear installations marks a dangerous precedent and will not go unanswered,” he said.
Araghchi criticized Washington for undermining diplomacy and giving what he called a green light to Israel’s military operations.
"They betrayed diplomacy, they betrayed negotiations...Iran has done nothing wrong, it is difficult to understand why we were attacked on a false claim."
Regarding the overnight US attacks on nuclear site, he said "the extent of damages are being investigated."
"The international community should condemn the attacks."
Tehran reserves its right under the UN Charter to defend itself and respond proportionately to acts of aggression, he added.
