French President Emmanuel Macron has called on the United States to pressure Israel to accept a plan for a 21-day ceasefire in Lebanon, saying an Israeli invasion would be a huge mistake, Reuters reports.

Israeli Foreign Minister Israel Katz had earlier rejected a French-US proposal for a 21-day truce. Prime Minister Benjamin Netanyahu said he had ordered the military to keep fighting with full force.

Macron, speaking in English, told the Canadian Broadcasting Corporation there was still time for Netanyahu to commit to the plan.

“And I do believe that the US now has to increase the pressure on the prime minister of Israel to do so,” he said. If Netanyahu said no, Macron said, France would raise the matter at the United Nations Security Council.

“We wait for all the partners to be very vocal and committed with us in order to send this clear message: Israel cannot invade Lebanon today. War is not possible in Lebanon today; it would be a huge mistake, a huge risk of escalation,” he said.
