If Iran attacks Israel directly in response to last week’s strike in Damascus, Israel will retaliate by striking targets in Iran, Sun reports.

Citing an unnamed “Western security official,” the report alleges that Israel has been conducting air force drills in recent days that include preparing to target Iranian nuclear facilities and other key infrastructure.

Both Damascus and Tehran blame Israel for last Monday’s raid in which seven members of the Islamic Revolutionary Guard Corps were killed, but Israel has not commented on the matter.
