The U.S. military struck Iran for the second time this week, carrying out attacks on a military facility on May 27, U.S. officials said. The skirmish occurred even as America and Iran continue to say they are seeking a negotiated deal to end the conflict. But the incident led to recriminations as both sides accused each other of violating the tenuous ceasefire.
The U.S. target was an Iranian drone station near Bandar Abbas in southern Iran, near the Strait of Hormuz, U.S. officials said. Earlier in the day, Iran fired five one-way attack drones, which the U.S. believed posed a threat around the Strait of Hormuz. They were shot down by American forces, and U.S airstrikes prevented the launch of a sixth drone.
“These actions were measured, purely defensive, and intended to maintain the ceasefire,” a U.S. official told Air & Space Forces Magazine on May 27.
U.S. officials originally said four Iranian drones were shot down, but revised that assessment upward on May 28.
Iran later retaliated for the American airstrikes, as its Islamic Revolutionary Guard Corps said it targeted an unidentified U.S. air base in the region. ”This response is a serious warning so that the enemy knows that aggression will not go unanswered, and if it is repeated, our response will be more decisive,” the IRGC said in a statement.
Kuwait said its air defenses intercepted drones and missiles in the early hours of May 28 local time. Later, U.S. Central Command added that Iran shot a ballistic missile towards the Gulf country that was intercepted by Kuwaiti forces. The U.S. operates Ali Al Salem Air Base in the country, which has previously been attacked during the conflict. It is unclear if that base was Iran’s intended target.
CENTCOM, in a May 28 statement, said that Iran’s ballistic missile launch was an “egregious ceasefire violation.”
“U.S. Central Command and regional partners remain vigilant and measured as we continue to defend our forces and interests from unjustified Iranian aggression,” the command added.
U.S. officials have yet to say which platforms the U.S. military used for its actions on May 27. American fighter jets regularly fly sorties near the Strait of Hormuz armed with both air-to-air and air-to-ground weapons.
This marks the second flare-up involving the Strait of Hormuz and targets near Bandar Abbas in three days. On May 25, the U.S. struck two IRCG vessels laying mines, sinking the ships. The Iranians shot at U.S. aircraft with surface-to-air missiles. The U.S. responded by attacking Iranian missile launchers. On May 26, Iran claimed it had downed a U.S. MQ-9 Reaper drone. American officials have not substantiated that account.
In both instances, U.S. officials have cast their actions as defensive in nature and not a major escalation in the three-month-old war.
The U.S. and Iran both insist they are adhering to the ceasefire, which was announced in early April, though they have sporadically exchanged fire. On May 7, the U.S. struck drone launchers, radars, and missile facilities in Iran after the U.S. military said three U.S. Navy destroyers were targeted by Iranian drones and missiles.
To enforce an ongoing blockade of Iranian ports, U.S. fighter planes have resorted to striking Iranian ships with gunfire and munitions. A U.S. Navy destroyer also disabled an Iranian ship with fire from its main gun during the blockade. The U.S. has turned around more than 100 ships since the blockade came into force on April 13.
The U.S. insists it is still pursuing a diplomatic path. “Diplomacy is always the first option,” Secretary of State Marco Rubio said during a Cabinet meeting on May 27 at the White House.
But President Donald Trump has threatened to renew military action should those talks fail.
During the meeting, Trump said Secretary of Defense Pete Hegseth and the U.S. military would “finish them off” if the U.S. could not agree to a deal with Iran.
