WorldUK and US tight-lipped after US aircraft leave second British airbase

More than a dozen US Air Force aircraft have left a second British base, weeks after US bombers departed RAF Fairford following a suspected Iran-linked security incident. The latest, a KC-135 refuelling aircraft, flew from RAF Mildenhall in Suffolk to Germany on Tuesday. The Wall Street Journal said the departures followed a further threat from Iran; the BBC has not independently verified that report.
