Explosions Heard on Iran’s Qeshm Island, Cause Unknown

Controlled detonation of unexploded “enemy” munitions believed to be responsible for Tuesday’s blasts, officials say, as region remains on high alert

TEHRAN / QESHM ISLAND — Explosions were heard on Iran’s strategic Qeshm Island on Tuesday afternoon, with initial reports from Iranian media indicating the cause was unknown and no official entity had immediately commented on the incident .

However, later updates from Iranian state-affiliated media suggested the explosions were the result of controlled detonations of unexploded “enemy” munitions. According to the semi-official Tasnim news agency, Iranian special forces were involved in deactivating the ordnance, which had not detonated during an earlier confrontation .

The blasts come just one day after Iranian air defenses on Qeshm Island were activated following the detection of drones in the area, which officials described as “American-Israeli hostile drones” .

The Explosions: Unclear Origins

The semi-official Mehr News Agency first reported the explosions on Tuesday afternoon, stating that the cause remained unknown. Shortly after, the state-affiliated Tasnim news agency provided more detail, citing Ahmad Nafisi, the Deputy Governor for political, security, and social affairs of Hormozgan Province.

According to Tasnim’s report, the explosions were caused by the “deactivation of the enemy’s unexploded ammunition” by Iranian special forces . This suggests that munitions—likely from Monday night’s engagement or previous strikes—required controlled detonation to eliminate the risk they posed. This explanation was not immediately corroborated by other Iranian state media outlets.

The Jerusalem Post noted that local media also reported that Qeshm Island’s air defense systems were activated again on Tuesday morning, indicating that the military remained on high alert ahead of the afternoon explosions . Videos circulating on pro-regime social media following the blasts showed protesters chanting “Death to Israel” and “Death to the United Arab Emirates” .

Monday Night’s Air Defense Activation

The explosions on Tuesday follow a significant military engagement on Monday night. Iranian air defense systems on Qeshm Island were activated after drones were spotted in the skies over the strategic island .

According to the political deputy governor of Hormozgan Province, the air defense activity was aimed at countering what he described as “American-Israeli hostile drones.” Officials stated that the sounds heard on the island earlier that night were caused by the activation of air defense systems and engagements with the drones . Authorities stressed that “the situation is fully under control,” and conditions on the island remained stable .

Why Qeshm Island Matters

Qeshm Island is the largest island in the Persian Gulf, located directly adjacent to the Strait of Hormuz—the narrow waterway through which approximately 20 percent of the world’s oil passes . The island houses significant military infrastructure, including an Islamic Revolutionary Guard Corps (IRGC) naval base and what analysts believe to be an underground “missile city” capable of threatening shipping in the strait.

The island has been a flashpoint throughout the US-Israeli war with Iran, which began on February 28. It has been targeted in previous strikes, with a freshwater desalination plant reportedly hit by US forces earlier in the conflict .

Regional and Diplomatic Context

The military activity on Qeshm Island comes at a precarious moment for the fragile ceasefire brokered by Pakistan that took effect on April 8. While major hostilities have been paused for more than five weeks, talks in Islamabad have failed to produce a lasting agreement .

President Donald Trump announced Monday that he had postponed a planned military strike on Iran at the request of Qatari, Saudi, and Emirati leaders who believe a diplomatic deal may be within reach. However, Trump also warned that he has instructed the US military to remain prepared for a “full, large-scale assault” if an acceptable deal is not reached [citation:previous coverage].

Iranian officials have said that an investigation is ongoing regarding the exact cause of the explosions on Qeshm Island and that further details will be released by relevant authorities . For now, the situation on the island is described as stable.
