White House spokesperson John Kirby told a briefing on Thursday that Israel had been "fully informed and fully aware of every word" in the ceasefire proposal and allies expected it would be taken seriously. The U.S. is Israel's longtime ally and biggest arms supplier.
French President Emmanuel Macron said he did not believe Israel's rejection was definitive. "It would be a mistake by the prime minister to refuse it because he would be taking responsibility for regional escalation," Macron told reporters in Canada.
"We will do everything to ensure this proposal is accepted," Macron said, adding that France was ready to call a new U.N. Security Council meeting to endorse the proposal.
Hundreds of thousands of people have fled their homes during the heaviest Israeli bombardment of Lebanon since a major war in 2006.
Hezbollah has
faced off against the Israeli military since the Shi'ite Muslim movement was created by Iran's Revolutionary Guards in 1982 to counter an Israeli invasion of Lebanon. It has since evolved into Tehran's most powerful Middle East proxy.
WASHINGTON STILL SEEKS CEASEFIRE
The White House said that U.S. and Israeli officials, including U.S. Mideast envoy Brett McGurk, were holding discussions on Thursday in New York.
U.S. Secretary of State Antony Blinken was due to meet with Israeli Minister for Strategic Affairs Ron Dermer.
In London, U.S. Defense Secretary Lloyd Austin warned there was a risk of all-out war in the Middle East, but a diplomatic solution was still possible.
"So let me be clear, Israel and Lebanon can choose a different path, despite the sharp escalation in recent days, a diplomatic solution is still viable," Austin said.
Hezbollah has fired hundreds of missiles at targets in Israel, including its commercial hub Tel Aviv, although Israel's aerial defense system has ensured the damage has been limited.
Israeli fighter jets on Thursday also hit infrastructure on the Lebanese-Syrian border to stop the transfer of weapons from Syria to Hezbollah in Lebanon, Israel's military said.
The Lebanese health ministry said most of the victims on Thursday were Syrians killed in the town of Younine in the Bekaa Valley. Lebanon is home to around 1.5 million Syrians who fled civil war there.
Hezbollah said in a statement it had struck the town of Kiryat Shmona in north Israel and an Israeli military northern command base, as well as using air defense weapons to force two Israeli warplanes back.
In Beirut, thousands of Lebanese have sought shelter in schools. In one, women could be seen leaning out of classroom windows, smoking cigarettes or airing out foam mattresses they had slept on this week.
Aid organizations were distributing clothes and food, and checking on medications needed by elderly people who fled too quickly to bring prescriptions with them.
