Tensions Escalate as Iran Closes Strait of Hormuz and Fires on Shipping; India Issues Protest
India summons Iranian envoy following attacks on merchant vessels as the Strait of Hormuz closure enters its seventh day.
Regional tensions have reached a critical point as Iran fully closed the Strait of Hormuz on April 18, 2026, reversing a brief period of restricted access. The Islamic Revolutionary Guard Corps reportedly used gunboats to fire on a merchant tanker, while a separate projectile damaged a container vessel. Both targeted ships were flying the Indian flag, prompting New Delhi to summon Iran’s ambassador in a formal diplomatic protest. The closure threatens approximately one-fifth of the world’s oil transit and has intensified the global energy crisis as the conflict enters its eighth week.
Diplomatic efforts appear to be stalling ahead of a critical April 23 deadline, when a fragile ceasefire is scheduled to expire. While Iran's parliament speaker noted some progress in negotiations with the Trump administration, he emphasized that "major gaps" remain. Meanwhile, Iranian Deputy Foreign Minister Saeed Khatibzadeh accused the United States of "miscalculations" that risk the global economy. In response to the maritime blockade, Iranian military officials warned that missile production remains unaffected and threatened retaliation if open hostilities resume.
Concurrently, Israel has advanced its military preparations, reportedly compiling a new list of strategic targets within Iran. This move aims to increase pressure on Tehran to make concessions regarding its nuclear program and to restore freedom of navigation through the Strait. U.S. Central Command confirmed that at least 23 vessels have been turned back toward Iran since the U.S. blockade commenced earlier this week.
