Washington, 14 April 2024 (dpa/MIA) - US President Joe Biden has urged Israel's Prime Minister Benjamin Netanyahu to carefully consider any Israeli retaliatory strike against Iran and the consequences this would have, sources in Washington say.

In a telephone conversation between the two leaders on Saturday evening, Biden made it "very clear" to Netanyahu that he needs to "think carefully and strategically about risks of escalation, a senior US government official said in Washington on Sunday.

This is something that is constantly being discussed with the Israeli side and other allies, the official said, noting that Biden also made it clear that the US would help Israel to defend itself.

Israel had made it clear to the US government in past talks that it was not looking for a significant escalation with Iran, the government representative said.

Iran's direct attack on Israel at the weekend is fuelling fears of a conflagration in the Middle East. International efforts were already being made on Sunday to defuse the situation.

Biden and leaders of the seven leading democratic industrialized countries (G7) discussed the crisis and condemned the large-scale attack in the strongest possible terms.

"We don’t want to see this escalate. We are not looking for a major war with Iran," John Kirby, communications director of the US government's National Security Council, said on Sunday, adding that the US president had been clear he was not seeking war with Iran.

The US would continue to help Israel defend itself, Kirby said, but said that how Israel responds now will be "up to them".

The US has been Israel's staunchest ally and biggest military supporter and has repeatedly reiterated its support as tensions escalated between Israel and Iran.

It was unclear on Sunday whether Israel would respond to Iran's unprecedented direct attack the previous day, involving some 300 missiles and drones in retaliation for a suspected Israeli strike at the start of the month.

Iran's "Operation Truthful Promise" was mounted in revenge for an airstrike on its embassy grounds in Damascus on April 1 in which two generals and others were killed. Israel is believed to have carried out the attack and has not denied responsibility.

Israel has been Iran's declared arch-enemy since the Islamic Revolution of 1979.

The decades-old tensions between the two countries have escalated following the outbreak of the Gaza war in October.
