In a speech in Jerusalem, Israeli PM Benjamin Netanyahu credited his nation's intelligence agencies with preventing "an unimaginable slaughter" linked to the Islamic State group.
Israel helped avert an alleged terror plot to bring down an Etihad Airways flight travelling from Sydney to Abu Dhabi, both nations have confirmed to the BBC.
In a speech in Jerusalem, Israeli PM Benjamin Netanyahu credited his nation's intelligence agencies with preventing "an unimaginable slaughter" linked to the Islamic State group.
Australian police last July charged two men over an alleged plan to blow up an Etihad plane.
A home-made bomb, hidden inside a meat-grinder, was due to be carried on to a flight but did not make it past security after the plan was aborted for an unknown reason.
Two Lebanese-Australian brothers were later arrested in Sydney and charged with "preparing for, or planning, a terrorist attack".
The AFP news agency said Israel did not reveal which flight was at the centre of its warning.
