Tehran will never cede control of Strait of Hormuz, senior Iranian politician tells BBC

A senior Iranian politician, Ebrahim Azizi, has told the BBC that Tehran will never relinquish control of the Strait of Hormuz, a strategic waterway crucial for global oil and gas shipments. Azizi, a former commander in Iran's Islamic Revolutionary Guards Corps (IRGC) and current head of the Committee for National Security and Foreign Policy, stated that Iran's control over the strait is an 'inalienable right' and that a new bill is being introduced to parliament to enshrine this control in law. The move has been met with concern from Iran's neighbors, who fear it could set a 'dangerous precedent' for other strategic waterways. The US has been pressing Iran to open the strait, with President Donald Trump threatening 'living in hell' if Iran fails to comply. The issue is set to be a key point in upcoming talks between the US and Iran in Pakistan.

European markets: Stoxx 600, FTSE, DAX, CAC, oil, Iran latest news

European stocks fell on Monday due to fears that escalating U.S.-Iran tensions could derail a fragile ceasefire between the two countries. The pan-European Stoxx 600 index was down 0.9%, with major European indices such as the FTSE 100, DAX, and CAC 40 also experiencing losses.

The US and Iran tensions escalated over the weekend with the US seizing an Iranian-flagged cargo ship in the Gulf of Oman. President Donald Trump announced the seizure, stating that the ship was under US Treasury sanctions due to its prior history of illegal activity.
