The United States launched a fresh wave of strikes against dozens of military targets in Iran on Thursday, retaliating for an attack on American forces in neighboring Jordan. Hours earlier, Iran struck a Chinese firm's building in northern Kuwait, killing a worker and severely damaging the structure, Kuwait's military said. Jordan's air defenses intercepted five missiles launched from Iran, according to the Jordanian military. The escalation widens the conflict across the Middle East, with the US hitting Iranian targets after a deadly drone attack on a US base in Jordan that killed three American service members. The Iranian strike on Kuwait occurred Thursday morning, according to Kuwaiti officials, who did not identify the nationality of the deceased worker. The building hit was owned by a Chinese company, as per Kuwait's military. Details of the US strikes, including locations and casualties, were not immediately available. The Biden administration has vowed to respond forcefully to attacks on US forces, with President Joe Biden stating earlier that the US would hold Iran responsible. The developments mark a significant expansion of hostilities, as Iran's military actions now directly target neighboring Gulf states beyond its ongoing proxy conflicts.
