TEHRAN, April 7 (Xinhua) -- Iran's Islamic Revolution Guards Corps (IRGC) on Sunday warned against any move by the United States to designate it as a "terrorist organization."

"If the Americans make such a silly move and endanger our national security, we will put reciprocal measures on our agenda based on the policies of Iran's Islamic establishment," Major General Mohammad Ali Jafari was quoted as saying by Press TV.

In case of such a decision by the United States, "the American army and U.S. security forces would not experience peace and calm in the Middle East anymore," Jafari said.

The United States has already blacklisted dozens of entities and individuals affiliated with the IRGC, but not the entire force.

Western media reported on Friday that the United States is expected to designate the IRGC as a terrorist organization.
