Iran’s Islamic Revolutionary Guard Corps said its navy and aerospace forces launched missile and drone attacks on US military sites in Kuwait and Bahrain on Sunday, sharply escalating a fragile ceasefire process and widening the military confrontation across the Gulf.
The IRGC said the operation was a response to US strikes on Iranian territory and warned that any violation of the ceasefire would halt diplomatic engagement under Clause 1 of the Islamabad Memorandum of Understanding. The statement marked one of Tehran’s clearest threats to suspend talks linked to the Pakistan-brokered framework, which had been intended to create a temporary pause in hostilities and reopen diplomatic channels after weeks of confrontation around the Strait of Hormuz.
The attacks targeted facilities used by US forces in two key Gulf states. Kuwait hosts major US military infrastructure, including Ali Al Salem Air Base and Camp Arifjan, while Bahrain is home to the US Fifth Fleet headquarters, a central command point for naval operations across the Gulf, Arabian Sea and parts of the Indian Ocean. Air defence systems were activated in Kuwait, while Bahrain reported security alerts after drones and missiles were detected over the Gulf.
There were no immediate confirmed reports of major US casualties. Early assessments from regional security officials indicated that several incoming projectiles were intercepted, while others landed near military zones or in open areas. Bahrain condemned the attack as a threat to its sovereignty and public safety. Kuwait also denounced the strike and said its armed forces remained on high alert to protect its territory and airspace.
The exchange followed a new round of US strikes on Iranian military infrastructure, including surveillance assets, communications systems, air defence sites, drone storage facilities and maritime capabilities. Washington said the strikes were carried out after attacks on commercial shipping near the Strait of Hormuz, where tension has disrupted insurance pricing, naval movements and shipping risk calculations.
The Strait of Hormuz remains the central pressure point in the confrontation. Roughly a fifth of global oil consumption passes through the narrow waterway, making even limited military incidents a concern for energy markets. Shipping companies have already faced higher war-risk premiums, slower transit planning and closer naval coordination as the confrontation has moved between Iranian territory, Gulf bases and commercial vessels.
The Islamabad memorandum had sought to prevent precisely this cycle of retaliation. Its ceasefire provisions were designed to stop direct military action while mediators worked on wider issues, including maritime security, sanctions relief, nuclear restrictions and guarantees for regional states hosting foreign forces. Sunday’s IRGC statement made clear that Tehran views US strikes as a breach of that process, while Washington has framed its actions as defensive responses to attacks on shipping.
The episode also places Kuwait and Bahrain in a more exposed position. Both countries have long maintained close defence relations with Washington while trying to avoid being drawn into open conflict with Tehran. Their governments have little room to tolerate attacks on their territory, but any forceful response could increase the risk of a wider Gulf confrontation.
Iran’s choice of targets appeared calibrated to send a military and political message without necessarily seeking mass casualties. By naming US sites in Kuwait and Bahrain, the IRGC signalled that bases used for operations against Iran could be treated as legitimate targets. That position is likely to alarm other Gulf governments that host US forces and depend on American security guarantees.
The US has significant assets across the region, including air bases, naval facilities and missile defence systems. Any sustained Iranian campaign against those sites would test regional air defence networks and could force Washington to expand its operations beyond limited strikes on Iranian military infrastructure.
Diplomatic channels remain active, but the space for mediation has narrowed. Pakistan’s role as a facilitator gave the ceasefire process a neutral venue, yet neither side appears willing to accept the other’s interpretation of restraint. Tehran argues that US strikes invalidate the pause. Washington argues that Iranian attacks on ships and bases cannot go unanswered.
The latest exchanges have also complicated efforts by Gulf states to keep energy flows moving. Tanker operators, port authorities and insurers are watching for signs of whether the strikes will remain symbolic and contained or develop into repeated attacks on infrastructure. Any prolonged disruption would feed into crude prices, freight costs and inflation expectations across importing economies.
