Iran’s Islamic Revolutionary Guard Corps claimed responsibility for a ballistic missile attack targeting a U.S. aircraft carrier and destroyer, according to reports from @KobeissiLetter. The claim, which was not independently confirmed in the report, would represent a further escalation in a conflict that has already included retaliatory strikes, warships, drones and missiles. Prediction-market odds of a full Iranian airspace closure by December 31 rose to 30.5%, up from 29.5% and 28% in earlier readings. The move reflects heightened concern that military tensions could affect Iran’s airspace decisions, ceasefire expectations and the prospect of further U.S. action. Statements from the Civil Aviation Organization of Iran, Iranian State Television, U.S. officials and President Donald Trump, along with verified reporting from Reuters or AP, will be watched for confirmation and indications of the conflict’s next phase.
