Herzog will give an address before the European Parliament to mark International Holocaust Remembrance Day on Thursday.
The European Parliament last week called on the EU to list the IRGC as a terrorist entry.
"We are ready to reciprocate. But we ask the Westerners to think carefully so that the window of opportunity for diplomacy is not closed," said the Speaker of Iran's Islamic Council.
