Iran’s UN envoy wrote to the Security Council accusing Israel of responsibility for a 28 January drone attack against a military facility in Isfahan. He also maintained that “the Israeli regime persists… its threats to use force against Iran’s critical infrastructure, including Iran’s peaceful nuclear facilities”, and asserted: “Iran reserves its legitimate and inherent right… to defend its national security and respond resolutely to any threats or wrongful actions by the Israeli regime, wherever and whenever deemed necessary”. The same day, a media outlet close to Iran’s Supreme National Security Council asserted that the components for UAVs used in the attack had “entered Iran with the participation and guidance of Kurdish opposition groups based in the Kurdistan region of Iraq… on the order of a foreign security service”. It further noted: “The necessity of preventing destructive and anti-security actions of Kurdish opposition groups based in the Kurdistan region of Iraq, has been repeatedly pointed out to the government of this country. The continuation of the terrorist activities of these groups against Iran shows that the Iraqi government has not yet been able to completely fulfill its legal responsibilities in this regard”.
