Tensions between the United States and Iran have escalated sharply in recent days, with American forces intensifying strikes across Iran and intercepting a vessel suspected of trying to break a blockade on Iranian oil exports. The surge in military activity has raised fears that the confrontation could tip into a wider war, jeopardising an interim understanding that had been meant to ease the crisis. Both governments have hardened their rhetoric even as they exchange fire, leaving little room for the diplomacy that briefly appeared possible earlier in the year.
The immediate flashpoint is the Strait of Hormuz, the narrow channel through which a large share of the world’s oil and gas passes. Early on 12 July, Iran’s Islamic Revolutionary Guard Corps declared the strait closed, saying it had fired warning shots at a ship that attempted to cross an unauthorised route. The United States, which has reinforced its naval presence in the Gulf, rejected the move and vowed to keep the waterway open. Tehran, in turn, urged its Houthi allies in Yemen to prepare to disrupt shipping in the Red Sea should Iranian energy facilities come under attack.
US Central Command said its forces had carried out dozens of strikes intended to degrade Iran’s ability to threaten vessels in the strait, following earlier waves of attacks on targets inside the country. American officials said one strike hit a tanker bound for Kharg Island, Iran’s principal oil-export terminal, after the vessel ignored repeated warnings. The Pentagon framed the operations as a defence of freedom of navigation, while Iranian commanders described them as acts of aggression that would not go unanswered.
Iranian state media reported that the strikes had killed more than 35 people and wounded over 300 in recent days, and officials condemned the attacks as barbaric. State outlets also said a cancer hospital in the country’s south-west had been evacuated because of nearby explosions. These casualty figures could not be independently verified, and the competing narratives from Washington and Tehran have made it difficult to establish an agreed account of events on the ground.
In response, Iran launched missiles and drones at several Gulf states that host American bases, with reports of attacks directed at the United Arab Emirates, Qatar, Kuwait, Oman and Bahrain. Local officials in Iraq said drones also struck near Erbil in the Kurdistan region, widening the geographic scope of the exchanges. Security forces in Basra briefly suspended crude-oil loading after a drone incident involving a tanker, though operations resumed within hours, underscoring how quickly the fighting has begun to ripple through regional energy infrastructure.
Iran’s military leadership warned that it was prepared to escalate further if the United States pressed ahead with threats against critical infrastructure. A spokesman for the armed forces said any foreign interference in the Strait of Hormuz would be treated as crossing a non-negotiable line, and he indicated that reopening the channel depended on adherence to a memorandum setting out transit conditions. Washington and Tehran have offered sharply different interpretations of that understanding, and the dispute over its terms has become a central obstacle to de-escalation.
The standoff has already reshaped the flow of trade through one of the world’s most important chokepoints. Maritime traffic through the strait has fallen sharply, with only a handful of vessels tracked crossing over one recent period, compared with the 18 to 22 daily transits recorded earlier in the month. The slowdown has rattled energy markets and revived concerns about the security of Gulf supply lines that much of the global economy depends on.
Oil prices have climbed accordingly. Brent crude has traded around $85 a barrel, its highest level in weeks, and analysts warn that a prolonged closure or a broadening of the conflict could push prices toward $100 or beyond. While US officials have hinted at further military action to secure the strait, many analysts caution that keeping it open by force would require a substantial ground commitment, complicating Washington’s options and raising the risk of a still deeper entanglement.
Despite American assertions that Iran remains open to talks, Iranian officials have rejected the idea that they will bend under military pressure. Tehran’s chief negotiator has cast the confrontation as an essential struggle against American influence, suggesting that any settlement would require a significant shift in Washington’s posture. The gap between the two sides’ public statements has widened, with each leadership entrenched in its position and wary of appearing to concede.
Efforts by outside states to lower the temperature have so far achieved little. Pakistan’s foreign minister said he had tried to open a channel between Washington and Tehran but acknowledged that the task was becoming harder as the strikes continued. For Yemen, already enduring one of the world’s gravest humanitarian emergencies after a decade of war, the prospect of renewed disruption in the Red Sea threatens to compound the suffering of millions who depend on imported food and fuel.
The consequences of the crisis extend well beyond the immediate military objectives of either side. Instability in the Gulf feeds directly into global energy prices and sharpens the geopolitical stakes across the Middle East, where alliances and rivalries are tightly interwoven. With both governments weighing their next moves and the international community watching closely, the coming days are likely to determine whether the confrontation can be contained or slides toward a broader and more destructive war.
