The strategic King Fahd Causeway, linking Saudi Arabia and Bahrain, has been shut as a precaution amid rising fears of potential Iranian strikes. The closure comes as Gulf nations brace for escalation in the ongoing conflict, with Iran previously warning of targeting infrastructure in countries seen as supporting US and Israeli operations. The move underscores growing regional anxiety, with critical transport and energy routes increasingly under threat. With deadlines looming and tensions at a peak, the coming hours are expected to be crucial for the Gulf region as both military and diplomatic developments unfold.
