Israel is preparing for retaliation from Iran as early as this evening, our US partner network reports.

Sources have told NBC that UK officials have heard Israel believes a missile attack could come tonight.

An Israeli military spokesman says the potential missile attack is expected to be widespread, according to Reuters.

US officials expect this Iranian response to involve more firepower than the response in April, NBC reports.

Officials say it’s expected to include a higher number of ballistic missiles than were used in April, and therefore the threat could be more significant.

Militia groups could also play a role here, including missile launches from the Houthis, officials say.
