Israel-Gaza-Lebanon live updates: Israel says it's now striking Iran

Defense Secretary Lloyd Austin on Wednesday denied reports that one of his senior staffers is under investigation by the FBI in connection with leaked Pentagon documents purportedly relating to Israel's planned retaliatory strike on Iran.

"There's no OSD [Office of the Secretary of Defense] official being named as a part of this investigation," Austin told reporters while in Rome, Italy. "So that is not true at this point."

"I've seen no evidence of that, or any indication that any OSD official will be implicated as part of this."

The Israel Defense Forces said warplanes conducted another night of airstrikes in the Lebanese capital targeting what it said were Hezbollah weapons storage, arms manufacturing and command center targets in the southern suburbs.

The airstrikes centered on Dahiya -- an area of south Beirut known as a Hezbollah stronghold.

More than 2,500 people have been killed by Israeli strikes in Lebanon since Oct. 7, 2023, with nearly 12,000 injured, according to tallies from the Lebanese Ministry of Public Health.

Secretary of State Antony Blinken departed Israel early Wednesday for Saudi Arabia -- the next stop on his latest Middle East tour.

Before boarding his plane in Tel Aviv, Blinken told reporters that Israel has now achieved most of its military objectives in Gaza -- including the elimination of Hamas leader Yahya Sinwar -- but at great cost to Palestinian civilians.

Blinken said it was time to end the conflict, having spent Tuesday meeting with Israeli leaders -- including Prime Minister Benjamin Netanyahu -- and the families of hostages in a bid to revive cease-fire and hostage release talks.

There is now a need to establish whether a post-Sinwar Hamas will be more open to a diplomatic resolution, Blinken said, plus to facilitate more aid into Gaza and to establish a concrete plan for the post-war governance of the territory.

Blinken said such questions would be part of his meetings with other Middle East leaders through this week.

During their meeting Tuesday, Secretary of State Antony Blinken asked Israeli Prime Minister Benjamin Netanyahu about reports that some Israeli officials wanted to seize control of north Gaza using controversial methods, according to a senior U.S. administration official.

Coined the "General's Plan" by media outlets, the idea would be to force evacuations of the area and assume anyone who stays behind is an enemy combatant and can be fired upon and starved.

The senior U.S. administration official said Blinken noted in the meeting that there's a "perception" that this method is official Israeli policy.

The official said Netanyahu and his top aide, Ron Dermer, denied that it was and said the perception was "deeply damaging" to their efforts.

"We did hear a very clear commitment that that is not their state of policy," the official told a reporter.
