IRAN'S Revolutionary Guard has warned Israel it will be "eradicated" in another "shockwave" following the bloody Hamas terror outrage.
It came after Iran's chilling threat of a pre-emptive strike on Israel stoked fears of an all-out war in the Middle East.
The fanatical regime threatened a strike in the "coming hours" and warned a Gaza invasion would open the "gates of hell".
Iran is a key backer of Palestine terror group Hamas, as well as Lebanon-based Hezbollah.
Ali Fadavi, deputy commander of the elite Revolutionary Guards Corps, said: "The resistance front's shocks against the Zionist regimes (Israel) will continue until this cancerous tumour is eradicated from the world map.
"Another shockwave is on the way if Israel does not end atrocities in Gaza."

Israel responded by blasting Gaza with non-stop airstrikes that have wiped out entire neighbourhoods and killed nearly 3,000 people.
Hundreds of thousands of soldiers are now preparing for a ground invasion to wipe out the terrorists in their underground lairs.
Tehran has repeatedly warned that a ground assault on Gaza would be met with a response from other fronts.

He told Al Jazeera: "It is highly probable that many other fronts will be opened.
"This option is not ruled out and this is becoming increasingly more probable."
