FEATURE | Interim Iran deal is over, Trump declares after fresh attacks

A top Iranian negotiator, parliament speaker Mohammad Baqer Qalibaf, accused the US of breaching the ceasefire agreement. He cited not only the latest US military strikes, but renewed oil sanctions, violations of Iranian "adjustments" in the Strait of Hormuz, and Israeli attacks against Lebanon.

"The era of bullying and extortion is over," Qalibaf said in a post on social media. "We don't fold."

Iranian media earlier reported explosions in Iran's main oil hub of Kharg Island, on Qeshm Island and in the southern port cities of Sirik and Bandar Abbas.

Iran's Press TV reported several blasts were heard in southern Kharg Island. CENTCOM made no mention of Kharg Island, from which Iran exports 90 per cent of its crude oil.

A US official told Reuters that strikes targeted Iranian air defence systems, coastal surveillance systems, surface-to-air missiles, anti-ship cruise missiles and drone launch sites.

No civilian deaths were reported in Iran.
