Iran cites US blockade, Israeli actions as ceasefire violations

Iran's Parliament Speaker Mohammad Baqer Ghalibaf said in a post on X on Monday that the US naval blockade on Iran and the escalation of Israeli military operations in Lebanon constitute clear evidence that Washington is not complying with the terms of the ceasefire.

Ghalibaf has previously posted on X that Tehran does not trust guarantees and words and will judge by actions, adding that Iran would not act unless the other side did first.

The US imposed a naval blockade on Iran on April 13, 2026, following the collapse of the Islamabad Talks. The US military said the blockade targets ships travelling to and from Iran, and has so far resulted in three ships being seized and 33 vessels intercepted, according to US Central Command. The blockade is estimated to be costing Iran $500 million daily, per US figures.

Iran has described the US counter-blockade as a potential "prelude to a violation of the ceasefire." Neither side has removed its blockade.

While Iran's core preconditions for a deal centre on lifting the US naval blockade, nuclear issues, and sovereignty guarantees, Tehran has also sought a halt to the conflict in Lebanon, where a mid-April ceasefire has failed to stop fighting between Israel and Iran-backed Hezbollah.

Israel struck Lebanon with more than 120 air strikes on May 27 in one of the heaviest days of bombing in weeks, according to Lebanese security sources.

US and Iranian negotiators were reported last week to have reached a tentative deal to extend the ceasefire and launch new nuclear talks over a 60-day window. Among the first issues to be negotiated is what will happen to Iran's highly enriched uranium, the country holds 440.9 kilograms enriched to 60% purity, a short technical step from weapons-grade levels, according to the International Atomic Energy Agency.

Even as the potential deal emerged, the US Treasury Department imposed additional sanctions on the Iranian military's oil sales arm, extending the Trump administration's economic pressure campaign on Tehran.
