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

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."

The Israel Defense Forces said Wednesday it killed a Hamas drone commander in an airstrike in the northern Gaza Strip.

The IDF said Mahmoud al-Mabhouh was Hamas’ UAV commander in the northern part of the territory.

The IDF said on social media that Mabhouh was responsible for launching unmanned aircraft towards Israel and against Israeli forces.

Israel launched its first airstrike on Beirut in nearly a week early on Wednesday.

The Israel Defense Forces claimed a strike "on strategic weapons belonging to the Hezbollah terrorist organization" in the capital's southern Dahiya suburb. It was the first such attack in the capital since a strike killed 22 people on Oct. 10.

"These weapons were stockpiled by Hezbollah in an underground storage facility in the area of Dahiya, a key Hezbollah terrorist stronghold in Beirut," the IDF wrote on X.

The strike came shortly after a new evacuation order issued online by IDF spokesperson Avichay Adraee for residents of the Haret Hreik area of southern Beirut.

Hezbollah's acting leader Deputy Secretary General Sheikh Naim Qassem said Hezbollah has the "right to target any point within the enemy's entity" in a prerecorded video address released Tuesday.

"The occupation seeks to destroy and eliminate everything that stands in its way, but the resistance is prepared to confront it and establish a new equation based on inflicting pain on the enemy," Qassem said. "We have the right to target any point within the enemy's entity, and we will choose the appropriate time and place to do so."
