With the Lebanese and Israeli ambassadors to the United States set to meet on Tuesday in Washington, Lebanon’s foreign minister said Beirut would use face-to-face negotiations to press for a ceasefire in the war that has complicated wider diplomacy to halt the conflict in the Middle East.

But the outlook for the meeting – a rare, face-to-face encounter between countries formally in a state ​of war – has been overshadowed, with Israel saying it won’t discuss a ceasefire while Hezbollah has objected to negotiations with Israel, reflecting sharply worsening ​political tensions in Lebanon.

On the ground in south Lebanon, the Israeli military completed its encirclement of the town of Bint Jbeil ⁠just over the border and had begun a ground assault there, an Israeli military spokesperson and Lebanese security sources said.

The Lebanese sources said Hezbollah fighters holed up ​inside were ready to fight to the death, citing the strategic and symbolic significance of Bint Jbeil, a Hezbollah stronghold, provincial capital, and gateway to surrounding villages.

Israel seeks to secure border strip

An Israeli military official said full operational control of Bint Jbeil would be achieved within days, and that only a small number of militants remained in the area.

On Sunday, Hezbollah said it had attacked Israeli forces in and around Bint Jbeil with rockets, artillery fire and suicide drones.

A foreign security official based in Lebanon said seizing Bint Jbeil would give ​Israel better control over the entirety of Lebanon’s southeastern border strip, leaving the western area of the border zone, which is largely forest and harder to clear.

Hezbollah ​opened fire on Israel in support of Tehran on March 2, igniting an Israeli offensive that Lebanese authorities say has killed more than 2,000 people and forced more than 1 ‌million people ⁠from their homes.

Israel says it aims to occupy south Lebanon up to the Litani River, which meets the Mediterranean about 30 km (20 miles) from Israel’s border.

Israel and the US have said the campaign against Hezbollah was not part of a fragile Iran-US ceasefire, though Pakistan’s prime minister, a key intermediary, had said the truce would include Lebanon.

While fighting in Lebanon has not stopped, Israel has launched no airstrikes on Beirut since Wednesday, when it pounded the capital ​during an onslaught that killed hundreds of ​people across the country.

The US ambassador ⁠to Lebanon, Michel Issa, will host Tuesday’s Washington meeting between Israeli ambassador Yechiel Leiter and his Lebanese counterpart Nada Hamadeh Moawad.

Lebanese culture minister Ghassan Salameh, speaking in an interview with Lebanese broadcaster Al Jadeed on Sunday, said seeking a ceasefire was ​the only substantive issue that Moawad had been authorised to discuss.

Israel’s embassy in Washington last week said the talks would ​constitute the start of “formal ⁠peace negotiations” and that Israel had refused to discuss a ceasefire with Hezbollah.

Lebanese Foreign Minister Youssef Raggi, a member of the staunchly anti-Hezbollah Lebanese Forces party, said Lebanon was trying to reach a ceasefire through direct negotiations.

In a phone call with German Foreign Minister Johann Wadephul, Raggi said, “Establishing this track has effectively established the separation between the Lebanese ⁠file and ​the Iranian track”, Raggi posted on X.

A senior Lebanese political source said the talks were taking ​place without any national consensus because both Hezbollah and its ally, Parliament Speaker Nabih Berri, opposed negotiations before a ceasefire. Another source familiar with their position said Lebanon should not sit at ​the table with Israel while “our people are being killed”.
