The US has said it will impose sanctions aimed at Iran’s missile and drone programme as well as the Revolutionary Guard and defence ministry in the next few days, and expects its allies to follow suit, in the wake of Tehran’s large-scale air attack on Israel at the weekend.

The national security adviser, Jake Sullivan, made the announcement on the same day Germany said it expected concerted EU sanctions, as the allies rushed to punish Iran economically while urging Israel not to launch military reprisals that could ignite an all-out war. Sullivan also said that a regional air defence and early warning system would be expanded to help defend against future attacks.

“In the coming days, the US will impose new sanctions targeting Iran, including its missile and drone program as well as new sanctions against entities supporting the Islamic Revolutionary Guard Corps (IRGC) and Iran’s Defense Ministry,” Sullivan said. “We anticipate that our allies and partners will soon be following with their own sanctions.”
