US Secretary of State Marco Rubio on Monday (local time) strongly criticised attempts by Iran to regulate or monetise the passage of vessels through the strategic Strait of Hormuz, warning that such actions would not be accepted by Washington and amount to an illegitimate claim over an international waterway.

In an interview with Fox News, Rubio said the United States would reject any effort to "normalise" a system in which Iran dictates access to one of the world's most critical maritime chokepoints.
