Iran Closes Strait of Hormuz Citing US Breach of MoU
Iran has announced the closure of the Strait of Hormuz to vessel traffic in retaliation for alleged US breaches of a recently signed Memorandum of Understanding and continued Israeli operations against Hezbollah in Lebanon amid escalating Iran tensions.
