Iran threatened to target recreational and tourist sites worldwide and insisted it was still building missiles. Friday’s show of defiance came nearly three weeks into U.S.-Israeli strikes that have killed a slew of Tehran’s top leaders and hammered its weapons and energy industries.

Iran launched two ballistic missiles at Britain’s Diego Garcia base in the Indian Ocean in a dramatic escalation of tensions, US officials have said.

Conservative leader Kemi Badenoch urged Prime Minister Keir Starmer to "come clean" about the details and accused him of "dithering and delaying" on the Iran conflict "from the outset".
