Gharibabadi accused Washington of taking "hostile actions" and violating its own commitments while indirect negotiations between the two countries were still underway. He said the talks, mediated by Qatar and Pakistan, have now reached an effective deadlock.

The deputy foreign minister stressed that Tehran's top priority is defending the country and vowed that Iran would respond decisively to any actions it considers aggression by the United States.

Earlier, Iran’s Foreign Ministry spokesperson Esmaeil Baghaei also said Iran has no plans to resume negotiations at this stage and will remain focused on national defense.

The statements came amid continued US strikes targeting Iranian positions, including sites near the Persian Gulf and the Strait of Hormuz as well as inland transportation infrastructure. Last week, President Donald Trump declared that the ceasefire agreement had effectively ended following an Iranian drone attack on a vessel transiting the Strait of Hormuz.

The US on Saturday carried out its eighth consecutive night of airstrikes, aimed at degrading Iran's capability to threaten commercial shipping passing through the Strait of Hormuz, while also retaliating for an attack by Iran's Islamic Revolutionary Guard Corps (IRGC) earlier that day on US troops stationed in Jordan, which killed two American service members.
