Iranian Supreme Leader Ayatollah Ali Khamenei in a speech on Wednesday after the attack on two bases said that this “slap in the face” to the U.S. was not sufficient, NBC News reports. The strikes came after the death of Iranian Gen. Qassem Soleimani, who was killed in a drone strike authorized by President Trump last week.

“They were slapped last night, but such military actions are not enough,” he said in the televised speech, Politico reports. “The corruptive presence of the U.S. in the West Asian region must be stopped.”

Khamenei also said in his speech that “the discussion about revenge is something else, this was just a slap in the face last night,” per NBC News.
