Iranian Foreign Minister Abbas Araghchi spoke by phone on Friday evening with U.N. Secretary General António Guterres.

During the conversation, he argued that Israel’s airstrikes “constitute a blatant violation of the sovereignty and territorial integrity of the Islamic Republic of Iran, as an independent U.N. member state, and are a clear act of aggression," according to a Fox News report. 

In a statement, Iran’s Foreign Ministry said the U.N. secretary general "voiced regret over the Israeli aggression and condemned its attacks against Iran, particularly the strikes on nuclear facilities at a time when talks between Iran and the U.S. were ongoing. He underscored his commitment to using U.N. mechanisms to help de-escalate tensions and restore peace and stability in the region."

The U.N. secretary general addressed the situation on X.

"Israeli bombardment of Iranian nuclear sites. Iranian missile strikes in Tel Aviv. Enough escalation. Time to stop. Peace and diplomacy must prevail," he wrote on Friday night.
