Israel-Gaza-Lebanon live updates: Israeli troops launch new West Bank operation

Hezbollah said in a Tuesday morning statement posted to social media that Naim Qassem was elected as the group's new secretary general in a vote by its decision-making Shura Council.

Qassem, 71, was born in the Lebanese capital Beirut. He was previously Hezbollah's deputy secretary general, serving in the role since 1991. Qassem has long been a prominent spokesperson for the Iran-backed militant organization.

His election followed Israel's assassination of former Secretary General Hassan Nasrallah in September and his presumed successor Hashem Safieddine in October.

Following Nasrallah's killing in Beirut, Qassem gave a video address in which he vowed that Hezbollah would continue its fight against Israel despite its significant military setbacks.

The Israel Defense Forces said Tuesday it attacked more than 110 targets in Lebanon and 40 targets in the Gaza Strip in the previous 24 hours.

Hezbollah targets in Lebanon included "launchers aimed at the rear of the state of Israel and weapons depots," the force wrote in a post to X.

In Gaza, the IDF said it attacked "terrorist cells, military buildings and other terrorist infrastructures."

UN Secretary-General António Guterres is "deeply concerned" by the two laws passed by the Israeli parliament Monday concerning the U.N. organization, UNRWA, he said in a statement Monday.

"UNRWA is the principal means by which essential assistance is supplied to Palestine refugees in the Occupied Palestinian Territory. There is no alternative to UNRWA," the UN Secretary-General said in the statement.

"The implementation of the laws could have devastating consequences for Palestine refugees in the Occupied Palestinian Territory, which is unacceptable," he added.

Israeli Prime Minister Benjamin Netanyahu released a statement on X Monday after legislation banning the U.N. agency for Palestinian refugees (UNRWA), a main provider of aid to Gaza, passed the Israeli parliament.

Israel is "ready to work with our international partners to ensure Israel continues to facilitate humanitarian aid to civilians in Gaza in a way that does not threaten Israel's security," Netanyahu said.

"UNRWA workers involved in terrorist activities against Israel must be held accountable. Since avoiding a humanitarian crisis is also essential, sustained humanitarian aid must remain available in Gaza now and in the future," the Prime Minister added.

The Israeli government has accused multiple UNRWA members of participating in Hamas' Oct. 7 terrorist attacks and having ties to Hamas. The UN conducted an investigation into the matter after the Israeli government's initial allegations, and fired multiple UNRWA staffers after the probe, according to the Associated Press.

UNRWA initially fired 12 staffers and put seven on administrative leave without pay over the claims. The UN then fired an additional nine staffers, according to AP.

The laws passed by the Israeli parliament Monday will take effect in 90 days and will likely be challenged by Israel's High Court.
