Hezbollah leader Naim Qassem rejected Lebanon’s preliminary peace agreement with Israel on Saturday, saying it heavily favors West Jerusalem.

Israeli and Lebanese delegations signed a US-backed agreement in Washington on Friday aimed at ending months of fighting between the IDF and Hezbollah in southern Lebanon. The deal was met with mass protests in the streets of Beirut.

Under the agreement, the Israel Defense Forces (IDF) agreed to gradually withdraw from some areas of Lebanon on condition that Hezbollah lay down its arms and hand over its strongholds to the Lebanese army.

In a statement, Qassem denounced the arrangement as “humiliating, shameful and invalid,” equating direct negotiations with Israel to “imposing surrender and handing over free concessions.”

Linking the IDF’s withdrawal from southern Lebanon to Hezbollah’s disarmament “crosses all red lines and turns Lebanon into a toy in the hands of the enemy,” Qassem said. He argued that any legitimization of Israeli control over Lebanese territory would pave the way for a long-term occupation or annexation.

Speaking at a news conference on Friday night, Israeli Prime Minister Benjamin Netanyahu hailed the agreement as “a major blow to Iran and Hezbollah.”

Although Israel pledged in the agreement that it had “no territorial ambitions” in Lebanon, Netanyahu said the IDF would stay in the country “as long as required.”

Israel expanded operations in Lebanon in early March after Hezbollah launched rockets at the Jewish state during the US-Israeli war on Iran. Israeli attacks have killed more than 4,200 people and displaced around 1 million, according to the Lebanese Health Ministry and the UN.

The US-Iranian talks hinge on developments in Lebanon, as Tehran has listed the end of Israeli operations as one of its key peace terms.
