Israel's military stops short of saying Israeli F-35s had been grounded on operational standby

Israel's military said on Thursday it was testing its fleet of F-35 fighters after receiving findings from U.S. investigators that a different model of the plane had a fuel systems flaw.

The military, on Twitter, stopped short of saying the Israeli F-35s had been grounded, describing them as remaining on operational standby.

The Pentagon said early Thursday that it had grounded all U.S. and international F-35 fighter jets made by Lockheed Martin Co so that fuel tubes can be examined, a Pentagon spokesperson said on Thursday.
