Iran has extended its closure of airspace to commercial flights amid ongoing tensions with the United States following a violent crackdown on nationwide protests. The move, which comes without official explanation, has disrupted global aviation as airlines reroute to avoid Iranian territory, a key corridor for East-West travel. The closure has raised concerns about possible military activity or heightened security risks, especially given Iran's past incidents of misidentifying civilian aircraft. Meanwhile, diplomatic rhetoric between Iran and the United States has shifted, with both sides signaling a preference for negotiation over conflict, even as activists warn of potential executions among detained protesters. The crackdown has resulted in a significant death toll, making it one of the deadliest periods of unrest in Iran in decades.
