The blockade came despite the Pakistan-brokered ceasefire.

Parliament speaker Ghalibaf said the US was unable to gain Iran's trust.

Iranian President Masoud Pezeshkian said an agreement is achievable if the American government abandons its totalitarianism.

Israel was not involved in the weekend negotiations.

The Lebanese Red Cross reported that their emergency workers came under direct targeting by an Israeli drone.

Global Energy Vulnerability
