Israel said it had killed three more Iranian commanders in its unprecedented bombing campaign against the Islamic Republic, which Foreign Minister Gideon Saar claimed had delayed Tehran's alleged progress towards a nuclear weapon by two years.
Israel's military said on Saturday that a strike in Qom south of Tehran successfully targeted top Iranian official Saeed Izadi, in charge of coordination with Hamas, adding two other commanders from Iran's Revolutionary Guards were also killed overnight.
As Israel continued to strike Iran's nuclear facilities and military targets, Saar said in an interview that by his country's own assessment, it had "already delayed for at least two or three years the possibility for them to have a nuclear bomb".
"We will do everything that we can do there in order to remove this threat," Saar told German newspaper Bild, asserting Israel's onslaught would continue.
Israel and Iran have traded wave after wave of devastating strikes since Israel launched its aerial campaign on June 13, saying Tehran was on the verge of developing a nuclear weapon –– an accusation the Islamic Republic has denied.
Israel said it had attacked Iran's Isfahan nuclear site for a second time after its air force announced it had also launched salvos against missile storage and launch sites in the centre of the country.
The army later said it was striking military infrastructure in southwest Iran.
US President Donald Trump warned on Friday that Tehran had a "maximum" of two weeks to avoid possible American air strikes, as Washington weighs whether to join Israel's campaign.
'Not prepared to negotiate'
Iranian Foreign Minister Abbas Araghchi arrived in Istanbul for a meeting of the Organisation of Islamic Cooperation to discuss the conflict.
Top diplomats from Britain, France and Germany met Araghchi in Geneva on Friday and urged him to resume talks with the United States that had been derailed by Israel's attacks.
But Araghchi told NBC News after the meeting that "we're not prepared to negotiate with them (the United States) anymore, as long as the aggression continues".
Trump, dismissive of European diplomatic efforts, also said he was unlikely to ask Israel to stop its attacks to get Iran back to the table.
"If somebody's winning, it's a little bit harder to do," he said.
Western powers have repeatedly expressed concerns about the expansion of Iran's nuclear programme, questioning in particular the country's accelerated uranium enrichment.
International Atomic Energy Agency chief Rafael Grossi has said Iran is the only country without nuclear weapons to enrich uranium to 60 percent.
However, he added that there was no evidence Tehran had all the components to make a functioning nuclear warhead.
Grossi told CNN it was "pure speculation" to say how long it would take Iran to develop weapons.
