Israel-Gaza updates: Netanyahu weighs plan to force civilians out of north Gaza

The U.S. State Department reissued its level 4 "do not travel" warning for Lebanon Saturday to include threats posed by "recent explosions throughout Lebanon, including Beirut."

The Department’s prevailing guidance for American citizens in the country—which is to "depart Lebanon while commercial options still remain available"—is unchanged from its last advisory issued in July.

"At this time, commercial flights are available, but at reduced capacity. If the security situation worsens, commercial options to depart may become unavailable," the advisory said.

Israel's chief military spokesman Brig. Gen. Daniel Hagari addressed the ongoing escalation between Israel and Hezbollah, saying in a statement Israel is currently conducting more strikes in Lebanon and has struck 400 “targets” on Saturday alone.

He also announced a change to defensive readiness for Israelis in Haifa and north of Haifa. They must now always be able to reach a shelter quickly and gatherings are limited to 300 people indoors and 30 people outdoors.

Asked about a possible ground invasion of Lebanon, he would only say, "Our mission is to return the residents of the north safely to their homes and for that we will do whatever it takes."

Hagari also addressed Gaza and said Israeli forces killed militants they believe were holding Hersh Goldberg-Polin and other hostages who were found dead last month.

The Israel Defense Forces said it struck 180 targets in Lebanon on Saturday, targeting "launcher barrels" that were ready for launching weapons toward Israel.

Four people have been injured in the Israeli strikes Saturday, one critically, the Lebanese Ministry of Health said.

The IDF said 90 launches were identified coming from Lebanon today but no casualties or damage were reported.

Hezbollah said they have launched nine aerial attacks toward Israel on Saturday.

The IDF said it “will continue operating to dismantle and degrade Hezbollah's capabilities and terror infrastructure.”

The Lebanese health ministry issued another update Saturday, bringing the total number of dead in Friday's Beirut strike to 37. It says first responders are continuing to search the rubble.

The dead include at least three children – ages 4, 6 and 10 – and seven women, the ministry said during a press conference earlier. Dozens more people have been wounded.

The Israel Defense Forces described the strike on Friday as a "targeted" assault.
