At least five emails determined to be classified were found among 2,800 documents stored on a laptop belonging to Anthony Weiner, whose then-wife Huma Abedin was deputy chief of staff to then-Secretary of State Hillary Clinton.

The State Department released hundreds of pages of materials Friday afternoon, including a total of eight pages classified at the 'confidential level,' the third most sensitive level the U.S. government uses.

The confidential classification level is applied to information whose unauthorized disclosure 'reasonably could be expected to cause damage to national security,'

The emails date from 2010, 2011 and 2012 and concern discussions with Middle East leaders including some from Israel, the United Arab Emirates, Hamas and the Palestinian Authority.

Large portions, including entire pages, were redacted before the documents' release.

Three of them were sent either to or from an address called 'BBB Backup,' which one email identifies as a backup of a Blackberry Bold 9700, presumably belonging to Abedin.

Court documents in a case between Judicial Watch and the State Department revealed that Huma Abedin (pictured today with son Jordan in New York City) had had 2,800 work-related emails saved on her estranged husband Anthony Weiner's laptop computer, and the documents include some classified emails

Another is a four-page 'call sheet' meant to guide Clinton through a sensitive phone call with Benjamin Netanyahu.

A third is a detailed rundown of issues Clinton was expecting to address during a call with Saud bin Faisal bin Abdulaziz Al Saud, who served as Saudi Arabia's foreign minister until 2015.

Only one small portion of that email was deemed classified by intelligence agencies that reviewed it before releasing it to the public.

The call sheet itself related mostly to the expected publication of a massive trove of U.S. diplomatic cables by the WikiLeaks organization.

'This appears to be the result of an illegal act in which a fully cleared intelligence officer stole information and gave it to a website. The person responsible will be prosecuted to the fullest extent of the law,' the call sheet advised her to say.

The then-secretary of state was warning the Saudis about impending leaks of 'details of private conversations with your government on Iraq, Iran and Afghanistan.'

The work-related emails and other documents were recovered from Weiner's computer last year by the FBI.

Civilians like Weiner, who was once a congressman but resigned in mid-2011, are prohibited from possessing or reading classified documents without a security clearance.

It's unclear whether Weiner had such a clearance while he was a public official, but he didn't serve on any House committees that would tend to expose him to sensitive foreign policy matters.

Friday's revelation will pose new public-image problems for Clinton, who has long faced tough questions over what the FBI has called her 'careless' handling of classified material.

The five sensitive documents on Weiner's laptop were designated 'classified' as officials pored through the material at the State Department's request.

But intelligence agencies warn that such documents are 'born classified,' meaning that their distribution is restricted whether or not they bear 'classified' stamps or other identifying marks.

Tom Fitton, president of the center-right government transparency group Judicial Watch, said Friday in a statement that he wasn't surprised Weiner's computer contained material he was forbidden to see.

'As we expected, there is classified information on Anthony Weiner’s laptop – thanks to Hillary Clinton’s illicit email games,' Fitton said.

'The Justice Department should launch an immediate criminal investigation.'

Fitton had tweeted on Thursday afternoon about whether the DOJ would 'finally take action on Clinton/Abedin misdeeds.'

Weiner handed his computer over to federal investigators as the FBI probed allegations that he had been sexting with an underage girl, a story first broken by DailyMail.com.

Judicial Watch president Tom Fitton surprised Clinton-watchers on Thursday by tweeting that the State Department would release a cache of materials on Friday related to her classified email scandal

Weiner was sentenced to 21 months in prison in September over the sexting case, and reported to a federal correctional facility early last month to begin service his time.

Judicial Watch has pressed in court for the public release of emails and other materials from Clinton's tenure as secretary of state.

The Freedom Of Information Act lawsuit that resulted in Friday's coming document-dump was filed in May 2015.

Fitton told DailyMail.com on Friday that it's 'outrageous' that Clinton and Abedin 'walked out of the State Department with classified documents and the Obama FBI and DOJ didn't do a thing about it.'

'We expect that we will be told that some of these classified materials were on Weiner's laptop, which is highly disturbing. Let’s hope it spurs a long needed Clinton special counsel or, at least, a serious criminal investigation,' he added.

Fitton believes Abedin, Clinton's longtime aide and deputy chief of staff, committed crimes by exchanging classified material in private emails connected to Clinton's now-infamous homebrew server.

'This is a disturbing development,' Fitton said in September after the State Department revealed how many government emails and other documents ended up on Weiner's PC.

'Our experience with Abedin's emails suggest these Weiner laptop documents will include classified and other sensitive materials.'

The FBI investigated Clinton's emails but closed the probe during last year's presidential election season.

In July 2016, then FBI Director James Comey hosted a press conference announcing that the FBI would recommend to the Department of Justice that Democratic nominee Clinton not be charged for mishandling classified information.

While Comey called Clinton 'extremely careless' in her handling of sensitive information he also said that no 'reasonable prosecutor' would bring a criminal case against her.

Then, in October, Comey wrote a letter to lawmakers informing them of new emails found on Weiner's computer – a revelation that threw Clinton's campaign into a tailspin.

Just days after Comey's letter was made public the FBI announced that nothing new had been found and that the case against Clinton had been closed again.

But Judicial Watch sued again, demanding '[a]ll emails of official State Department business received or sent by former Deputy Chief of Staff Huma Abedin from January 1, 2009 through February 1, 2013 using a non-'state.gov' email address.
