Israeli officials on Sunday called President Donald Trump’s demand for Israel to halt strikes on Lebanon a “resounding slap in the face” as Israel’s strikes on Beirut targeting Hezbollah threatened to throw a wrench into Trump’s plan for a peace agreement by the end of the day.

Trump had made clear his intention to have a deal to end the war in Iran signed by Sunday’s end, but Israel launched strikes on a Hezbollah command center in Beirut, which led Iran to question the U.S. commitment to a peace deal. Trump then condemned Israeli strikes on Lebanon, saying they were unwarranted because the initial Hezbollah strikes did not kill or injure any Israelis.
