European ministers and Iran's top diplomat met on Friday in Geneva, Switzerland, as President Donald Trump continued to weigh US military involvement and worries rose over potential strikes on nuclear reactors.
European officials expressed hope for future negotiations, and Iranian Foreign Minister Abbas Araghchi said he was open to further dialogue while emphasising that Tehran had no interest in negotiating with the US while Israel continued attacking.
"Iran is ready to consider diplomacy if aggression ceases and the aggressor is held accountable for its committed crimes," he told reporters.
No date was set for the next round of talks.
Israeli Prime Minister Benjamin Netanyahu said Israel's military operation in Iran would continue "for as long as it takes" to eliminate what he called the existential threat of Iran's nuclear program and arsenal of ballistic missiles.
But Netanyahu's goal could be out of reach without US help.
Iran's underground Fordo uranium enrichment facility is considered to be out of reach to all but America's "bunker-buster" bombs.
Trump said he would put off deciding whether to join Israel's air campaign against Iran for up to two weeks.
The war between Israel and Iran erupted June 13, with Israeli air strikes targeting nuclear and military sites, top generals and nuclear scientists.
At least 657 people, including 263 civilians, have been killed in Iran and more than 2000 wounded, according to a Washington-based Iranian human rights group.
Iran has retaliated by firing 450 missiles and 1000 drones at Israel, according to Israeli army estimates.
Most have been shot down by Israel's air defences, but at least 24 people in Israel have been killed and hundreds wounded.
Israel's defence minister said on Saturday it killed a commander in Iran's Revolutionary Guard who financed and armed Hamas in preparation for the October 7, 2023, attack on Israel that sparked the 20-month long war in Gaza.
Saeed Izadi, who was commander of the Palestine Corps for the elite Iranian Quds Force, was killed in an apartment in the city of Qom.
Addressing an emergency meeting of the UN Security Council, Rafael Grossi, the head of the International Atomic Energy Agency, warned against attacks on Iran's nuclear reactors, particularly its only commercial nuclear power plant in the southern city of Bushehr.
Israel has not targeted Iran's nuclear reactors, instead focusing its strikes on the main uranium enrichment facility at Natanz, centrifuge workshops near Tehran, laboratories in Isfahan and the country's Arak heavy water reactor southwest of the capital.
Iran previously agreed to limit its uranium enrichment and allow international inspectors access to its nuclear sites under a 2015 deal with the US, France, China, Russia, Britain and Germany in exchange for sanctions relief.
But after Trump pulled the US out of the deal during his first term, Iran began enriching uranium closer to weapons-grade levels and restricting access to its nuclear facilities.
Iran has long maintained its nuclear program is for peaceful purposes.
Israel said its warplanes hit dozens of military targets across Iran on Friday, including missile-manufacturing facilities, while an Iranian missile hit Israel's northern city of Haifa, wounding at least 31 people.
Iranian state media reported explosions from Israeli strikes in an industrial area of Rasht, along the coast of the Caspian Sea.
Israel's military had warned Iranians to leave the area around Rasht's Industrial City, but with Iran's internet shut off - now for more than 48 hours - it's unclear how many people could see the message.
The Israeli military believes it has destroyed most of Iran's ballistic missile launchers, contributing to the steady decline in Iranian attacks.
But several of the roughly three dozen missiles that Israel said Iran fired on Friday slipped through the country's aerial defences, setting off air-raid sirens across the country and sending shrapnel flying into a residential area in the southern city of Beersheba, where a hospital was hit on Thursday.
