Iran claims its air defenses have shot down another U.S. reconnaissance drone over southern Iran as fighting with the United States intensifies. Tehran said the unmanned aircraft was intercepted after entering Iranian airspace, while separate reports claimed fresh U.S. missile strikes hit areas near Abadan. The claims have not been independently verified. Iran also warned that the attacks would not go unanswered, with senior officials urging U.S. forces to leave the region immediately. Is the conflict entering an even more dangerous phase?
