Israel-Gaza-Lebanon live updates: NGOs report 'horrifying' Gaza conditions

At least six people were killed and 43 injured in an Israeli strike on Nabatieh, Lebanon, which hit the town's municipal headquarters during a meeting, according to Lebanese Minister of the Interior Bassam Mawlawi. The city's mayor was among those killed.

"⁠The targeting of the municipality building in Nabatieh occurred during the coordination of relief work and the preparation of aid for distribution to the residents in the cities and villages of the region who are steadfast in the face of the war they are being subjected to and against Lebanon," Mawlawi said in a statement.

The town's mayor reportedly told Reuters that he would not leave the town after an evacuation notice was issued by Israel for Nabatieh on Oct. 3.

Israel said it struck dozens of Hezbollah targets in Nabatieh and dismantled underground infrastructure in southern Lebanon, including a tunnel network under the town. Israel has not commented on strike whether the took place during the coordination of relief efforts.

At least six people were killed and 43 injured in an Israeli strike on the southern Lebanese city of Nabatieh on Wednesday -- including the city's mayor -- according to Lebanese health officials.

The strike hit the town's municipal headquarters and came as officials met to coordinate relief efforts, Interior Minister Bassam Mawlawi said.

"⁠The targeting of the municipality building in Nabatieh occurred during the coordination of relief work and the preparation of aid for distribution to the residents in the cities and villages of the region who are steadfast in the face of the war they are being subjected to and against Lebanon," Mawlawi said in a statement.

Search and rescue teams are continuing to search for survivors under the rubble of the two buildings targeted in the strike.

Israel's Coordinator of Government Activities in the Territories organization said more than 145 aid trucks entered Gaza on Tuesday and 50 on Wednesday, amid allegations that Israel has failed to facilitate humanitarian relief in the northern part of the strip.

COGAT said that four bakeries are operational in northern Gaza, though it is unclear whether humanitarian organizations have been able to distribute any aid into the north.

Dozens of aid organizations published a joint statement Wednesday saying no aid has been allowed into northern Gaza since Oct. 1.

Thirty-eight NGOs signed a new appeal to the international community to stop Israel's latest military operation in northern Gaza, which they said has "escalated to a horrifying level of atrocity."

"Northern Gaza is being wiped off the map," the organizations said, describing the Israel Defense Forces' order for civilians to leave the northern part of the territory as "forced displacement under gunfire."

Around 400,000 people are estimated to be subject to the north Gaza evacuation order. Hospitals -- already "overwhelmed" according to the NGOs -- and their staff are also being ordered to evacuate, with the IDF declaring the area a dangerous combat zone.

Israeli officials have denied they are implementing the so-called "Generals' Plan," a proposal by retired Israeli military leaders to put north Gaza under siege and declare anyone who does not evacuate to be a valid military target.

"The world cannot continue to stand by as the Israeli government commits these atrocities," the NGOs wrote. "We demand an immediate ceasefire and an end to Israel's illegal occupation."
