The Israeli military said it launched strikes on Hezbollah targets in Beirut on Sunday, potentially complicating efforts to finalize a deal to end the U.S.-Iran war. Smoke rose over the Lebanese capital, and the Civil Defense said it retrieved three bodies and six wounded people from the rubble.

Iran threatened a military response.

The deal in its current form is a deep disappointment to Israel’s government, which has been sidelined in negotiations led by Pakistan and others. The last time Israel struck the Beirut suburbs a week ago, it set off the most serious escalation of fighting between Iran and Israel since the tenuous ceasefire took hold April 7.

There was no immediate White House comment on Israel’s strikes. U.S. President Donald Trump, who had said the deal could be signed Sunday, has pressed Israeli Prime Minister Benjamin Netanyahu to stop hitting Lebanon hard while a deal is near, but the prime minister has defied him.

Netanyahu’s office said the strikes were in response to Hezbollah attacks on northern Israel. Israel’s military said Hezbollah launched three projectiles, releasing footage where an audible boom was followed by rising smoke. There was no immediate comment from the Iranian-backed Hezbollah.
