Iran mocks Israel claims of downing drone

Separately, a Revolutionary Guards' official on Saturday said he could not confirm the report because Israelis were "liars", Ninenews reports.

Israel said it launched air strikes against air defences and Iranian targets in Syria on Saturday and the Syrian army claimed to have hit an Israeli F-16 that crashed in northern Israel in a major escalation of tension.

"Reports of downing an Iranian drone flying over Israel and also Iran's involvement in attacking an Israeli jet are so ridiculous," state TV quoted Iran's foreign ministry spokesman Bahram Qasemi as saying.
