Iran's Acting Foreign Minister Ali Bagheri Kani and Slovenian Foreign Minister Tanja Fajon on Sunday exchanged views on the assassination of Hamas Political Bureau Chief Ismail Haniyeh.

During their phone conversation, Bagheri Kani said that Iran would undoubtedly use its "legitimate and inherent" right to defend its security, sovereignty and territorial integrity to create deterrence against Israel's "acts of aggression" and ensure security and stability in the region.

Bagheri Kani highlighted the importance of Iran's role in maintaining peace, stability and calm in the West Asia region. He also said it is necessary to stop the "genocide" by Israel in Gaza and condemned its "unlawful" actions, according to a statement released by the Iranian Foreign Ministry.

For her part, Fajon said that her country condemns any violation of international law.

She expressed hope that all parties would exercise self-restraint and take steps "wisely and tactfully" towards ensuring stability in the region.

Haniyeh, who was in the Iranian capital Tehran to attend the inauguration of Iran's new president, was killed together with his bodyguard in an airstrike before Wednesday dawn when their residence in Tehran was hit, according to Iran's Islamic Revolution Guards Corps, which said Israel had carried out the "terrorist attack" and vowed "a harsh and painful response."
