The European Union’s top diplomat said Tuesday there were “no excuses” for Israel to refuse to accept a ceasefire with the Lebanese militant group Hezbollah, saying all its security concerns had been addressed in the U.

Josep Borrell, the outgoing EU foreign policy chief, called for increased pressure on Israel to blunt extremists in the government who are refusing to accept the deal. Speaking on the sidelines of a Group of Seven meeting in Italy, Borrell warned that if a ceasefire is not implemented, “Lebanon will fall apart.”

Senior EU officials expressed relief at the announcement of a ceasefire on Tuesday between Israel and the Lebanese Hezbollah militia, while French President Emmanuel Macron sees it as a chance to stabilize Lebanon.
