Four oil tankers have reportedly been hit by explosions in the Strait of Hormuz, escalating tensions in the strategically important waterway. Two supertankers were disabled following explosions on Wednesday, while two more vessels were reportedly struck by mines on Thursday. Iran said the tankers had ignored warnings and caught fire in the restricted shipping route. The incidents have raised fresh concerns over maritime security and the potential disruption of global oil supplies through one of the world's most vital energy corridors.
