The U.S.-Iran conflict has entered a delicate phase of 'armed diplomacy' over the last 24 hours. While President Trump has indicated a willingness to wait a few days for a response to U.S. demands, military enforcement remains active. U.S. Central Command confirmed that American forces boarded the Iranian-flagged tanker M/T Celestial Sea in the Gulf of Oman on suspicion of blockade violations. The vessel was searched and released after being directed to alter its course away from Iranian ports. Simultaneously, Iran has reportedly opened a new front of economic pressure by demanding 'protection fees' for submarine communication cables in the Strait of Hormuz, threatening the region's digital infrastructure. On the diplomatic front, mediation efforts led by Pakistan have deepened, with Interior Minister Mohsin Naqvi meeting directly with IRGC commanders in Tehran to stabilize maritime traffic. Turkish President Recep Tayyip Erdogan also joined the de-escalation effort, publicly endorsing the ceasefire extension in a call with President Trump. Despite these regional interventions, the Trump administration maintains that no sanctions relief will be granted before a formal agreement, while Iranian President Masoud Pezeshkian continues to demand 'mutual respect' over 'pressure and threats.' Global oil markets mirrored the cautious optimism, with crude prices falling 6% as traders anticipate a possible 30-day negotiating window.
