BEIRUT (AP) — Israel’s air force targeted sites belonging to Hezbollah in Lebanon, including in the country's eastern Bekaa Valley, late on Monday as Israeli Prime Minister Benjamin Netanyahu vowed to intensify attacks on the Lebanese militant group.

Netanyahu's warning came as Hezbollah has been firing fiber optic drones — a weapon used widely in the war in Ukraine — at Israeli forces in southern Lebanon and northern Israel in recent weeks.

“We will hit them. It’s true that they are shooting drones at us, fiber optic drones. We have a special team working on that and we will solve that too,” Netanyahu said in a video posted on social media. “What this requires of us now is to increase the blows, to increase the intensity. We will smite them hip and thigh.”

Lebanon’s state-run National News Agency said that after Netanyahu's post, some residents started leaving Beirut’s southern suburbs where Hezbollah has large presence. The agency also said several airstrikes hit the eastern town of Mashghara in the Bekaa region on Monday night.

Meanwhile, Hezbollah said that it carried out eight attacks earlier in the day, including a drone attack on Israeli troops in Misgav Am in northern Israel.

The daily attacks between Israel and Hezbollah have been ongoing despite a U.S.-brokered ceasefire in place since April 17.

A U.S. State Department official said earlier on Monday that Hezbollah has ignored repeated requests to stop firing at Israel, including a recent ultimatum. The official, who was not authorized to talk to the media and therefore spoke on condition of anonymity, added that Israel will never be expected to passively absorb attacks on its forces and civilians.

Since the ceasefire went into effect, Hezbollah has fired over a thousand drones and over 700 rockets to try and derail ongoing negotiations between Lebanon and Israel, the official said, adding that “the status quo is untenable.”

Last month, Lebanon and Israel began their first direct talks in more than three decades with meetings held in Washington. Lebanese and Israeli military officials are to meet again on Friday, at the Pentagon, to discuss the ceasefire. Israel and the United States are seeking to have Hezbollah disarmed.

The State Department official said the direct Lebanon-Israel talks and the implication that Lebanon stands to get significant support from the U.S. is a threat to the Iran-backed Hezbollah, along with a challenge to its narrative of resistance against Israel.

“A successful ceasefire led by the government of Lebanon would strip Hezbollah of their power and their narrative,” the official said.

Earlier Monday, an Israeli airstrike on the southern village of Kfar Rumman killed four people and wounded three, the Lebanese NNA reported. It said Israeli drone strikes on other parts in the south — including one on a road near the municipality of Kfar Rumman — killed three people.

The Israel military said that throughout the day, it struck more than 70 Hezbollah infrastructure sites.

The latest Israel-Hezbollah war began on March 2, when Hezbollah fired rockets into northern Israel, two days after the U.S. and Israel began their attacks on Iran.

More than 3,000 people have been killed in Lebanon in the latest fighting, according to the Lebanese Health Ministry. Also, 22 Israeli soldiers and a defense contractor have been killed in or near southern Lebanon, and two civilians have been killed in northern Israel, according to Netanyahu’s office.
