Israeli F-35 stealth fighters penetrated Iranian airspace several times in the last two months, a Saudi-run news outlet reports.
The unverified report in London-based Elaph says the jets successfully evaded Russian and Iranian radars during the exercises.
The report says Israel and the US also carried out secret exercises over the Red Sea simulating a strike on Iran from the sea and air and the seizing of Iranian warships.
In January Elaph, citing the same unnamed source, reported on Israel carrying out massive refueling drills over the Mediterranean, also aimed at practicing for an Iran strike.
The report comes as the US and world powers edge closer to reentering the Iran nuclear deal, which Israel opposes.
