Israel struck Tehran, targeting the infrastructure of the Iranian regime, the military said in a brief ‌statement that did not provide details. Iran fired a barrage of missiles at Israel, the Israeli military said, triggering air raid sirens in Tel Aviv as explosions from air defence interceptors echoed across the city.

The United Arab Emirates also reported a "missile threat" early on Friday, as Muslims began celebrating the Eid al-Fitr holiday, marking the end of the holy month of Ramadan.

Kuwait said an oil refinery in the Gulf state was hit by a drone attack.

Energy prices jumped on Thursday after Iran responded to an Israeli attack on a major gas field by hitting Qatar's Ras Laffan Industrial City, which processes around a fifth of the world's liquefied natural gas, causing damage that will take years to repair.
