Level 1 — Absolute Beginner
The United States and Iran attack each other again early on Monday, July 13, 2026. This is part of a long fight between the two countries.
Iran says a very important sea path is now closed. The path is called the Strait of Hormuz. Many oil ships use this path every day.
Iran makes a new group. It is called the Persian Gulf Strait Authority. This group says the US caused the closure. But the US says something different. The US says its attacks stop Iran from hurting ships in the strait.
The news makes oil prices go up. People around the world feel worried about what will happen next.

Level 2 — Elementary
The United States and Iran exchanged new attacks overnight into Monday, July 13, 2026, continuing a pattern of strikes and counterstrikes between the two countries. The two sides gave conflicting statements about whether a key waterway, the Strait of Hormuz, is open for ships.
US Central Command said American forces carried out a new round of strikes aimed at reducing Iran's ability to threaten ships in the strait. The strikes hit air defense systems, radar sites along the coast, missile and drone equipment, and small boats.
Iran, however, announced that it has closed the Strait of Hormuz completely. Iran also created a new government agency, the Persian Gulf Strait Authority, whose job is to collect tolls from ships and manage traffic through the strait.
The new agency posted on the social media platform X that passage through the strait 'is currently not possible,' and blamed the United States for the closure. The dispute comes just days after President Trump said the ceasefire between the US and Iran was over, and it pushed oil prices up by about 3.46% as markets grew nervous.

Level 3 — Intermediate
The United States and Iran traded fresh strikes overnight into Monday, July 13, 2026, prolonging a tit for tat military exchange that has defined their confrontation for months. Both governments issued starkly conflicting declarations about the status of the Strait of Hormuz, a narrow waterway that sits at the center of the dispute.
US Central Command stated that American forces conducted a new round of attacks intended to degrade Iran's capacity to threaten commercial shipping passing through the strait, targeting air defense systems, coastal radar installations, missile and drone capabilities, and small boats used by Iranian forces.
Iran responded by declaring the strait closed outright and unveiling a newly formed agency, the Persian Gulf Strait Authority, tasked with collecting tolls and coordinating transit through the waterway, a move that effectively asserts Iranian control over passage. The agency posted on X that passage through the strait 'is currently not possible,' placing responsibility for the closure squarely on Washington.
The escalation follows President Trump's declaration, just days earlier, that the ceasefire between the US and Iran had collapsed. Oil prices jumped roughly 3.46% in response, rattling markets that depend on the strait, one of the world's most vital corridors for oil shipments, as the broader 2026 Strait of Hormuz crisis, which began in February, shows no sign of resolution.

Level 4 — Advanced
The United States and Iran traded fresh salvoes overnight into Monday, extending a tit for tat exchange that has become the defining rhythm of their confrontation, even as the two governments offered starkly irreconcilable accounts of whether the Strait of Hormuz, the world's most consequential maritime chokepoint for oil, remains navigable.
US Central Command characterized the latest American strikes as intended to degrade Iran's capacity to menace commercial traffic transiting the strait, describing a campaign that targeted air defense batteries, coastal radar installations, missile and drone infrastructure, and small patrol boats.
Tehran's response was not merely rhetorical. Iran declared the strait closed and unveiled the Persian Gulf Strait Authority, a newly minted bureaucratic apparatus charged with levying tolls and choreographing transit, an institutional gambit that recasts a military standoff as an administrative fait accompli. Writing on X, the agency insisted that passage through the strait 'is currently not possible,' attributing the closure entirely to Washington.
The standoff has escalated in the days since President Trump pronounced the ceasefire between the two countries defunct, and it sent oil prices lurching roughly 3.46% higher as traders priced in the risk to a corridor through which a substantial share of the world's seaborne crude transits. The episode is merely the latest chapter in the broader 2026 Strait of Hormuz crisis, an escalating confrontation that has simmered since February.
