Two months of uneasy quiet just broke. At noon Eastern Time on Tuesday, U.S. warplanes began striking Islamic Revolutionary Guard Corps targets across Iran — the second direct military clash between Washington and Tehran in three days, after tanker attacks and an attempted sea-mine operation pushed the Strait of Hormuz back to the brink. Here's what's known so far, in five questions.
1. What Just Happened?
At 12:00 p.m. ET on Tuesday, U.S. forces began striking Islamic Revolutionary Guard Corps (IRGC) targets inside Iran, U.S. Central Command announced. CENTCOM said the strikes follow recent attempted IRGC attacks on commercial shipping in the Strait of Hormuz and on American service members deployed to the region. Explosions were reported around the Strait as the operation got underway. A pair of oil tankers had come under attack in the shipping route shortly before the strikes were launched.
2. Why Now — What Triggered This Round?
Iranian forces had reportedly tried to launch rockets carrying sea mines into the Strait of Hormuz over the weekend, prompting the U.S. to strike two IRGC rocket launchers on Sunday — the first U.S.-Iran clash in roughly a month. Iran responded with an air attack on U.S. military bases in Jordan. Reports had also surfaced that Trump was weighing a CENTCOM plan for periodic strikes to stop Iran from rebuilding radar and missile capabilities around Hormuz, which appears to have set the stage for Tuesday's action.
3. How Has Iran Responded, And What Is It Saying?
The IRGC, in a statement carried by state-linked Fars News Agency, warned that "every attack will be met with even more devastating responses." Foreign Ministry spokesman Esmaeil Baqaei called the U.S. strikes a "strategic mistake of its own making," accusing Washington of "mistaking negotiation for dictation" and of repeatedly fabricating pretexts — from "imminent threat" claims to nuclear allegations — to justify military action. Iran maintains it will abide by its nuclear treaty obligations. Iranian officials said two people were killed in Sunday's U.S. strikes; Jordan and the UAE said the Iranian weapons fired at them were intercepted or caused no damage.
4. Is This A Full-Scale Return To War, Or Something More Limited?
Officially, it looks contained for now. President Trump has downplayed the broader conflict as "a relatively small war," calling Iran a "failed nation," while saying Tuesday's response would "hit them hard." Washington's stated approach in recent weeks has leaned toward economic pressure over military escalation — though this is the second direct military exchange in three days after about a month of relative quiet.
5. What Else Is Moving Alongside The Strikes — Diplomacy, Markets, Sanctions?
Diplomatically, Iranian President Masoud Pezeshkian, meeting Vladimir Putin at the Shanghai Cooperation Organization summit in Kyrgyzstan, said Iran would "immediately take reciprocal action" if the U.S. returns to the terms of a June memorandum of understanding meant to end hostilities. On the economic front, Treasury Secretary Scott Bessent, speaking at the G20 summit, teased new sanctions on banks allegedly facilitating Iranian business, citing expanded Treasury authorities across digital assets, aviation, and maritime trade. Markets reacted sharply to Sunday's clash — oil prices rose nearly 3% and U.S. stocks fell — and similar moves are likely as Tuesday's strikes are digested.
