"European Commission president Ursula von der Leyen said she told Israeli Prime Minister Benjamin Netanyahu on Sunday that diplomacy was ultimately best on Iran, but stopped short of calling for an immediate ceasefire.
Von der Leyen said that she agreed with Netanyahu in a telephone call that "Iran should not have a nuclear weapon, without any question."
Von der Leyen has previously criticised Israel's actions in Gaza, but said that Iran's non-compliance with the UN nuclear watchdog meant Israel "has the right to defend itself".
"Iran is the principal source of regional instability," she added."
