United States President Donald Trump on Monday warned Israeli Prime Minister Benjamin Netanyahu that Israel could lose American support if it continued to attack Lebanon and Iran, Axios reported.

Israel on Monday said that it had struck military targets in western and central Iran in retaliation for Tehran’s missile strike on the country.

On Tuesday, Israel had been preparing for the biggest wave of strikes on Iran since the ceasefire came into effect on April 8, with dozens of sensitive targets to be attacked, the news outlet quoted two unidentified Israeli officials as saying.

Trump then called Netanyahu and asked him to stop the strike.

“I said, ‘[Netanyahu], you better be careful, or you will be on your own very soon,” Trump told Axios.

The call ended with Netanyahu agreeing to stand down if the Iranians did not attack, the news outlet reported.

This came as Israel and Iran said that they would pause attacks following their most serious escalation since the ceasefire.

The Iranian military’s joint command said Monday that it was halting its offensive operations. However, it added that if Israel or its supporters carried out any further “aggression and hostile acts”, including in southern Lebanon, then “much more severe and crushing measures than before will follow”, AP reported.

Netanyahu also said that the fighting had stopped “after we hit the terror regime in Tehran.” However, he added: “If the terror regime in Iran makes the mistake and returns to attacking us, we will respond with force.”

Netanyahu also said that Israel is continuing to operate against Iran’s ally, the Iran-backed Lebanese militant group Hezbollah, and that Israel “has full right to self-defense and we will exercise it to the full extent necessary,” AP reported.

Tehran had on Monday warned of retaliation after Israel struck the southern suburbs of Lebanese capital Beirut on Sunday despite Washington’s recent calls for restraint. Israel claimed that Hezbollah had fired at northern Israel earlier in the day.

Israel’s strike on Beirut came days after Israel and Lebanon agreed on June 3 to renew a ceasefire and continue negotiations for a broader peace agreement amid tensions in West Asia, the two countries said in a joint statement issued with the US.

However, Hezbollah had rejected the deal. The group is not part of the Lebanese government and was not a participant in the negotiations.

After Washington and Tel Aviv attacked Iran on February 28 and killed Iranian Supreme Leader Ali Khamenei, Hezbollah launched an attack on Israel in retaliation on March 2.

While a US-brokered ceasefire took effect in Lebanon on April 17, attacks had continued, which strained the agreement.

Iran has repeatedly warned that it would suspend its dialogue with Washington if Israeli military operations in Lebanon continued.
