Iran’s Islamic Revolutionary Guard Corps (IRGC) claimed on Sunday that it had launched a large-scale missile and drone operation targeting eight US military installations across the Gulf region, describing the attacks as a “decisive response” to what it called renewed American aggression against Iranian territory.

In a statement, the IRGC said its Navy and Aerospace Force jointly conducted the operation between 2am and 3am local time, targeting eight “key US military installations,” including the Ali Al Salem Air Base in Kuwait and the headquarters of the US Fifth Fleet in Bahrain’s Salman Port.

The IRGC said the operation involved ballistic missiles and drones, claiming that the targeted facilities had been destroyed.

The claims could not be independently verified.

According to the statement, the operation was launched in response to US attacks earlier on Sunday against five Iranian coastal outposts.

“The aggressor enemy, whose very nature is characterised by breaking commitments and violating agreements, attacked five coastal outposts of the Islamic Republic in the early hours of today under the pretext of responding to the IRGC Navy’s confrontation with a trespassing vessel,” the statement said.

Earlier, the US said that it had carried out strikes against 10 targets in Iran on the orders of President Donald Trump, marking the latest escalation in a conflict that has continued despite a fragile ceasefire.

In a statement posted on social media, the US Central Command (CENTCOM) said American military aircraft targeted Iranian military infrastructure following an attack on a commercial vessel on Saturday.

According to CENTCOM, the strikes targeted Iranian “surveillance infrastructure, communication systems, air defence sites, drone storage facilities and minelayer capabilities.”

The US military later clarified that the operation involved strikes against 10 Iranian military targets at multiple locations in and around the Strait of Hormuz.

US officials said the strikes were conducted in response to threats against maritime security.

The IRGC also warned that maritime traffic through the Strait of Hormuz remained under Iran’s responsibility under a recently signed Pakistan-mediated memorandum of understanding between Tehran and Washington.

“Henceforth, vessels found to be in violation will be dealt with more firmly than before,” the statement said.

The force further warned that any future attacks, regardless of their stated justification or scale, would be met with a “crushing response.”

“The enemy should understand that violating the ceasefire constitutes a breach of Clause One of the Islamabad understanding and will result in the complete suspension of all related processes,” the statement added.

The IRGC statement came after the United States Central Command (CENTCOM) announced that it had carried out fresh strikes against targets inside Iran, saying the attacks were launched in response to the targeting of a commercial oil tanker.

Shortly after the announcement, Iran’s state broadcaster IRIB, citing an informed military source, reported explosions in Sirik County in the southern province of Hormozgan.

According to the report, several projectiles struck a telecommunications tower near the village of Tahrouyi in Sirik.

Residents on Qeshm Island also reported hearing multiple explosions.

The latest escalation follows an incident on Friday in which the IRGC Navy reportedly fired warning shots at a vessel accused of using an unauthorised route through the Strait of Hormuz after ignoring repeated warnings.

CENTCOM subsequently announced strikes against Iranian military targets, prompting Tehran to launch retaliatory attacks against American military positions in the region.

Tehran says it responded to the attacks with at least 100 retaliatory strikes and has continued to react to what it describes as subsequent ceasefire violations.
