Israeli strikes on Lebanon Monday killed more than 490 people, including more than 90 women and children, Lebanese authorities said, in the deadliest barrage since the 2006 Israel-Hezbollah war. The Israeli military warned residents in southern and eastern Lebanon to evacuate ahead of its widening air campaign against Hezbollah.

Thousands of Lebanese fled the south, and the main highway out of the southern port city of Sidon was jammed with cars heading toward Beirut in the biggest exodus since 2006.

Lebanon's health ministry said the strikes killed 492 people, including 35 children and 58 women, and wounded 1,645 people — a staggering one-day toll for a country still reeling from a deadly attack on communication devices last week.

The death toll far surpassed that of Beirut's devastating port explosion in 2020, when hundreds of tons of ammonium nitrate stored in a warehouse detonated, killing at least 218 people and wounding more than 6,000.

In a recorded message, Israeli Prime Minister Benjamin Netanyahu urged Lebanese civilians to heed Israeli calls to evacuate, saying “take this warning seriously.”

“Please get out of harm's way now,” Netanyahu said. “Once our operation is finished, you can come back safely to your homes.”

Israel's military spokesman, Rear Adm. Daniel Hagari, said the army will do “whatever is necessary” to push Hezbollah from Lebanon's border with Israel.

Hagari claimed Monday's widespread airstrikes had inflicted heavy damage on Hezbollah. But he would not give a timeline for the ongoing operation and said Israel was prepared to launch a ground invasion of Lebanon if needed.

“We are not looking for wars. We are looking to take down the threats,” he said. “We will do whatever is necessary to do to achieve this mission. We hope to do it as shortly as we can.”

Hagari said Hezbollah has launched some 9,000 rockets and drones into Israel since last October, including 250 on Monday alone.

The military spokesman said Israeli warplanes struck 1,300 Hezbollah targets Monday, destroying cruise missiles, long- and short-range rockets and attack drones. He said many were hidden in residential areas, showing photos of what he said were weapons hidden in private homes.

“Hezbollah has turned southern Lebanon into a war zone,” he told a news conference.

Israel estimates Hezbollah has some 150,000 rockets and missiles, including guided missiles and long-range projectiles capable of striking anywhere in Israel.
