President Donald Trump urged restraint on Sunday as fresh military activity threatened to complicate efforts to finalize what has been described as a long-awaited agreement aimed at ending the U.S.-Iran conflict.

The warning came after Israel’s military said it launched strikes on Hezbollah targets in Beirut, raising concerns that renewed escalation could interfere with ongoing diplomatic efforts.

Smoke was seen rising over the Lebanese capital following the strikes, while Civil Defense officials reported recovering three bodies and six wounded individuals from the rubble.

Iran responded by threatening military action, adding another layer of uncertainty to already delicate negotiations.

Trump addressed the situation on social media, emphasizing how close negotiators may be to a breakthrough. “We are very close to a Deal that will bring peace to the region,” he wrote, before adding a direct warning: “Let’s not blow it!”

According to the report, the current form of the agreement has left Israel’s government dissatisfied after being sidelined in negotiations led by Pakistan and other parties.

The latest strikes also carry recent historical weight. The last Israeli operation targeting Beirut’s suburbs one week earlier triggered the most serious escalation between Iran and Israel since the ceasefire that took effect on April 7.

Trump, who had previously indicated the agreement could be signed Sunday, has reportedly pushed Israeli Prime Minister Benjamin Netanyahu to avoid major military action in Lebanon while negotiations remain active. However, the report states that Netanyahu has continued forward despite that pressure.

For now, diplomacy and military action appear to be moving in opposite directions—and the closer negotiators get to a deal, the higher the cost of any move that risks pulling the region back from the negotiating table.
