Trump threatens more strikes on Iran as Tehran warns of 'fearless' response

What Happened

On Tuesday night into Wednesday, the US and Iran engaged in the worst exchange of strikes since a 14-point memorandum of understanding (MoU) was signed on 17 June. US Central Command (Centcom) said it launched 'powerful' strikes in response to attacks on three tankers in the Strait of Hormuz; Iranian state media claimed eight members of the country's army were killed at Bandar Abbas and Bushehr. Iran retaliated by targeting US military sites in Bahrain and Kuwait, according to its own statements. President Donald Trump, speaking at a Nato summit in Turkey, declared the ceasefire agreement 'over', called Iranian leaders 'scum' and 'cuckoo', and threatened more strikes. Iran's Foreign Minister Abbas Araghchi vowed a 'fearless' response, while senior adviser Ali Akbar Velayati warned of 'immediate' retaliation. The US also revoked its temporary suspension of sanctions on Iranian oil sales. Negotiations for a permanent end to the war had been paused following the death of Supreme Leader Ayatollah Ali Khamenei in earlier US-Israel strikes, with his burial set for Thursday in Mashhad.

Why It Matters

The breakdown of the ceasefire threatens a direct US-Iran military escalation that could destabilise the Strait of Hormuz, disrupt global oil supplies, and widen the regional conflict. Trump's dismissal of diplomacy, combined with Iran's defiant rhetoric and the suspension of talks after Khamenei's death, sharply narrows the path to de-escalation and could fracture the fragile consensus within the Axis of Resistance and among Western allies.

Watch For

Immediate focus on whether the US follows through with Trump's threat of further strikes, and Iran's 'immediate response' as promised by Velayati. The burial of Khamenei on Thursday may temporarily pause hostilities but could also trigger a calibrated retaliation. Centcom's naval posture in the Strait of Hormuz and any new tanker incidents will be critical. Diplomatically, note whether special envoy Steve Witkoff or Jared Kushner resume backchannel talks despite Trump's dismissal, and monitor Nato and GCC reactions to the sanctions snapback and oil price volatility.
