Saudi Arabia's crucial Red Sea oil route faces a fresh scare after a mystery projectile reportedly struck a tanker near the kingdom's strategic Yanbu port. The crew was safe, but the incident raises questions over who launched the projectile and whether Saudi shipping is facing a widening threat. Yanbu has become even more important as tensions around the Strait of Hormuz threaten Gulf energy flows. The strike also comes as Pakistan Army chief Asim Munir arrives in Tehran amid Houthi-Saudi tensions. Could Munir's Iran mission help prevent another dangerous regional escalation?
