Washington CNN —The US is on high alert and actively preparing for a “significant” attack that could come as soon as within the next week by Iran targeting Israeli or American assets in the region in response to Monday’s Israeli strike in Damascus that killed top Iranian commanders, a senior administration official tells CNN. Senior US officials currently believe that an attack by Iran is “inevitable” – a view shared by their Israeli counterparts, that official said. A forthcoming Iranian attack was a major topic of discussion on President Joe Biden’s phone call with Israeli Prime Minister Benjamin Netanyahu on Thursday. As of Friday, the two governments did not know when or how Iran planned to strike back, the official said. At least six Syrian citizens were also killed, Iranian state television reported on Tuesday.
