"It is not at all acceptable that one of our neighbors that has deep relations with us ... becomes a center for creating threats against the Islamic Republic," said Foreign Ministry spokesman Saeed Khatibzadeh.
"Iran will not tolerate that a center near its borders becomes the center for sabotage, conspiracy and sending terrorist groups to Iran," he said at his weekly press conference in Tehran.
Iran's Islamic Revolution Guards Corps (IRGC) on Sunday said that it had pounded an Israeli "strategic center" in the northern Iraqi city of Erbil with "powerful precision missiles" in retaliation for Israel’s strike on Syria that killed two IRGC officers last week.
Kurdish authorities in Iraq’s semi-autonomous region said a dozen ballistic missiles had landed in Erbil in the pre-dawn cross-border attack.
Khatibzadeh said that the federal government of Iraq "has been notified several times ... not to allow Iraq's borders with Iran to become insecure".
"Iran expects the central government of Iraq to end this situation once and for all and not allow its borders to be abused," he added.
“The United States has conducted military operations against Iran from inside Iraq, and the occupying Zionist has sabotage bases there. What we have announced to the Iraqi government is that the key to friendship is respect for mutual interests and sovereignty. Our warnings were, however, ignored and one of the centers of conspiracy and sabotage was responsibly struck,” Khatibzadeh said.
The IRGC had already warned on Tuesday that Israel "will pay” for the killing of its officers in Syria where Iran maintains a military advisory mission.
“Once again, we warn the criminal Zionist regime that the repetition of any mischief will face harsh, decisive and destructive responses," IRGC’s Sunday statement said.
On Thursday, Iran’s permanent mission to the United Nations had written to the UN secretary general and the Security Council, saying Tehran "reserves its inherent right to self-defense, under Article 51 of the United Nations Charter, to respond to such criminal act whenever it deems appropriate”.
