Israel-Gaza-Lebanon live updates: American hostage's father makes plea to Biden and Trump

Israel said it conducted strikes on 20 targets in Beirut, including components of Hezbollah's military and financial systems.

"Among the targets struck were a Hezbollah aerial defense unit center, an intelligence center, command centers, weapons storage facilities, an operations room, an artillery storage facility, and terrorist infrastructure sites," Israel said in a statement.

Israel also targeted Al-Qard Al-Hassan Association -- a nonprofit that gives out loans -- alleging it is used by Hezbollah to collect and store funds.

Israel had sent evacuation orders about 20 minutes before the strikes hit. The IDF said they are attacking Hezbollah in Beirut on "a large scale." Black smoke was still visible and covering part of Beirut hours later.

The strikes began just minutes before Israeli Prime Minister Benjamin Netanyahu was set to meet with his cabinet to discuss a cease-fire deal with Hezbollah.

Earlier Tuesday, there were three other strikes in Beirut.

Fresh airstrikes shook Beirut's southern Dahiya suburbs on Tuesday morning, with the Israel Defense Forces claiming to have targeted six Hezbollah targets including infrastructure sites used by the group's coast-to-sea missile unit.

The IDF said it struck around 30 Hezbollah targets in Dahiya over the past week. The suburb -- parts of which are close to the city's international airport -- is known as a Hezbollah stronghold and has borne the brunt of months of near-daily airstrikes on the Lebanese capital.

The strikes followed soon after an IDF warning for residents to evacuate parts of Dahiya.

Lebanese authorities said that 3,768 people in Lebanon had been killed by Israeli strikes as of Sunday.

The Israel Defense Forces said Tuesday that its forces conducted operations near Lebanon's Litani River -- the waterway around 18 miles of the Israeli border which Israeli leaders have demanded serve as a buffer keeping Hezbollah units out of the country's south.

Reaching the Litani would mark the deepest penetration of Israeli forces into Lebanon since the IDF withdrew from the country in 2000. Israeli troops did not push up to the Litani in the 2006 war with Hezbollah.

Soldiers "raided several terrorist targets, engaged in close-quarters combat with terrorists, located and destroyed dozens of launchers, thousands of rockets and missiles and weapons storage facilities" in operations in the Litani River region, the IDF said in a post to X.

Lebanon's Ministry of Public Health said Tuesday that the death toll from Israel's military operations in the country had risen to 3,768 people as of Sunday.

Another 15,699 people have been wounded since renewed fighting between the Israel Defense Forces and Hezbollah began on Oct. 8, 2023, the ministry said.

Israel continued airstrikes on Monday night and Tuesday morning even amid reports of an imminent cease-fire deal. Lebanon's National News Agency reported six people killed in multiple attacks in the southern Nabatieh Governorate.

IDF spokesperson Avichay Adraee also issued fresh evacuation warnings for Beirut's southern Dahiya area on Tuesday morning ahead of planned airstrikes there.
