The United States military launched an eleventh consecutive night of strikes against Iran on July 21, 2026, with US Central Command (CENTCOM) announcing the operation began at 7 pm Eastern Time (2300 GMT) on Tuesday. Explosions were reported across a broad sweep of Iranian territory, from northwestern Tabriz to southern coastal areas near the Strait of Hormuz. Al Jazeera

CENTCOM stated the strikes are designed to continue degrading Iran's ability to threaten commercial shipping in the Strait of Hormuz. The narrow waterway handles a substantial share of global oil shipments, and the US and Iran are competing for control of it. The campaign has now run nightly since early July.

The geographic scope of the latest strikes appears to have widened. An attack on Tabriz, in Iran's northwest, would mark a departure from the prior strike pattern, which had largely focused on southern Iran and the Strait of Hormuz area. Iranian semi-official media also reported activity much farther afield. Residents of northeastern Tehran reported hearing air defence activity, according to Iran's Fars news agency. Several explosions were heard around Sirik in southern Iran, Fars also reported. Iran's Tasnim news agency reported explosions being heard in parts of Bushehr, the southern province that hosts Iran's sole operational nuclear power plant.

The strikes resumed following the breakdown of a June 17 memorandum of understanding agreed between the US and Iran. The terms of that MOU and the circumstances of its collapse are not detailed in the available reporting, but its failure cleared the way for a sustained nightly bombing campaign. US strikes on Iran in July began after Qatari and Saudi oil tankers were attacked in the Strait of Hormuz, Al Jazeera reported on July 8. CENTCOM struck approximately 90 Iranian military targets during the July 7-8 round alone, according to a CENTCOM press release.

The tempo has been relentless. CENTCOM released footage on July 18 showing US forces launching strikes, and published press releases on July 16, July 18, July 19, and July 20 announcing successive waves. President Donald Trump said Iran was hit "very hard" after the ninth night of strikes, as CNN reported on July 19. The Associated Press reported that satellite images showed US and Israeli strikes targeting shipyards and missile facilities in Iran. Reuters confirmed that the US military said late on July 20 it had finished its latest round.

Iran has not absorbed these strikes in silence. Since the resumption of US attacks this month, Iran has repeatedly attacked Gulf countries including Kuwait, Bahrain, and Qatar. On Tuesday, the Kuwaiti army said its air defences were intercepting an Iranian drone attack. Iran's Supreme Leader Ayatollah Ali Khamenei warned that US strikes would result in "irreparable damage." Those threats have materialized in drone and missile attacks on US-aligned Gulf states, extending the conflict's geography well beyond the bilateral US-Iran theater.

The campaign also builds on a prior phase of US military action against Iran's nuclear infrastructure. Secretary of Defense Pete Hegseth and Chairman of the Joint Chiefs of Staff Dan Caine previously praised the success of US strikes on three Iranian nuclear sites. The strike on Iran's Fordow Fuel Enrichment Plant used 30,000-pound GBU-57 "massive ordnance penetrator" bombs, the Defense Department reported. Hegseth has stated that the US plans major strikes on Iran, signaling that the current tempo reflects a deliberate, sustained posture rather than a retaliatory spasm.

The broader context here matters for several reasons. The expansion of strike targets to Tabriz, if confirmed, suggests US planners are reaching beyond Iran's southern coastal military infrastructure and into the country's northwest, where significant military and industrial assets are concentrated. That widening, combined with reports of air defence activity near Tehran, raises the question of whether the campaign is evolving from a focused maritime-degradation mission into a broader effort to dismantle Iran's conventional military capacity. The parallel Iranian attacks on Kuwait, Bahrain, and Qatar indicate that Tehran's strategy is to hold Gulf Arab states at risk, presumably to pressure them to constrain US access to bases and airspace. Whether that calculus succeeds depends on Gulf states' willingness to absorb attacks without curtailing cooperation with Washington. The June 17 MOU's collapse, and the speed with which both sides returned to open hostilities afterward, suggests that whatever diplomatic framework existed was shallow and that both parties have settled into a posture where military escalation is the default rather than the exception.
