The United States launches new airstrikes against Iran early Thursday, and Iran responds with attacks targeting U.S.-allied countries in the Middle East, in an intensifying cycle of retaliation. Multiple reports describe back-and-forth attacks that follow similar strikes from the previous day, with heightened activity on Thursday. Sirens reportedly sound at least three times in Bahrain, where the U.S. Navy’s 5th Fleet headquarters is located, and additional reports note sirens in other countries including Kuwait and Qatar.

The exchanges come amid an interim diplomatic effort aimed at helping end the war. Sources say the renewed attacks threaten the interim deal and the broader ceasefire environment, as the earlier flare-ups have already raised concerns about the sustainability of any pause in hostilities.

While the reports provide overlapping accounts of the escalation and regional impacts, they generally do not offer full detail on specific target locations or damage. The situation remains dynamic as both sides continue to trade actions across the region.
