European Commission Ursula Von der Leyen called for negotiations with Iran and an end to hostilities on Tuesday (March 24).

Von der Leyen condemned Iran’s attacks on civilians and commercial shipping, saying that the closure of the Strait of Hormuz was unacceptable. She did not condemn the United States' and Israel's actions that began the war.

"The situation is critical for the energy supply lines worldwide," she added, during a news conference with Australian Prime Minister Anthony Albanese in Canberra.

Iran denied on Monday (March 23) that it had engaged in negotiations with the United States, after President Donald Trump postponed a threat to bomb Iran's power grid because of what he described as productive talks with unidentified Iranian officials.
