Videos posted online Monday appear to show Iranian police firing live ammunition and tear gas at demonstrators protesting the government accidentally shooting down a Ukrainian International Airlines jet, The Associated Press reports.

Tehran originally denied any involvement in last Wednesday's crash, which killed all 176 people on board, but later admitted the Islamic Revolutionary Guard Corps had mistakenly shot down the plane. The incident occurred shortly after Iran fired ballistic missiles at two Iraqi air bases hosting U.S. troops, launched in response to President Trump authorizing an airstrike that killed Iranian Maj. Gen. Qassem Soleimani.

Protests were held throughout the weekend, with demonstrators speaking out against what they consider a cover-up by the government. One video shot on Sunday night shows protesters near Tehran's Azadi Square fleeing after a tear gas canister fell by them, AP reports. Another video shows a woman being carried away from the scene, with a person shouting that she had been shot in the leg by live ammunition. Late last year, Iranians took to the streets to protest against high gas prices, and the unrest reportedly led to the deaths of more than 300 people.

Rob Macaire, the British ambassador to Iran, attended a vigil in Tehran for the plane crash victims on Saturday night. He left once the vigil became a protest, and was detained about 30 minutes later; he was released after speaking with Iran's deputy foreign minister. Britain called this a "flagrant violation of international law," while Iran's Foreign Ministry considered Macaire's presence at the gathering "illegal and inappropriate." Catherine Garcia

President Trump is heavy on the plans and light on the specifics.

In a wide-ranging interview with The Wall Street Journal on Tuesday, Trump confirmed he was considering adding more countries to his travel ban, said he would impose tariffs on European automobiles, and added he was working on a middle-class tax cut. Not that he said which ones, when that would happen, or just what the cut entailed, respectively.

Reports first indicated the Trump administration was planning an addition to its travel ban earlier this month. Trump told the Journal his administration does have plans to add more countries to the list later this month, but wouldn't say more. He also said his administration is "looking at many different things" when it comes to his longstanding — and now faded — push to oust Venezuelan leader Nicolás Maduro.

Trump went on to say he's still working on a trade agreement with the EU, saying "I'm going to put tariffs on them if they don't make a deal that's a fair deal." He was asked when that would happen but didn't answer, just saying "they know what the deadline is." And as for policies back in the U.S., Trump said "we're talking a fairly substantial… middle-class tax cut" that'll be revealed in 90 days. The plan's implementation dependent on him being reelected, Republicans holding the Senate, and the GOP taking back the House — the third bit being very unlikely in a presidential election year.

The Wuhan virus, which broke out in China last month and has so far infected more than 300 people and killed six, has reportedly reached U.S. shores, a federal source told CNN.

The Centers for Disease Control and Prevention is expected to announce Tuesday that a person in Washington state has been infected, making the U.S. the sixth country to experience the outbreak of the respiratory illness, along with China, Taiwan, Japan, Thailand, and South Korea. The patient was hospitalized with pneumonia last week after having traveled to eponymous Wuhan, China, where the outbreak appears to have originated at a seafood and poultry market, The New York Times reports.

A lot remains unknown about the virus, although the latest development strengthens the hunch that it spreads from person to person. One of the most pressing questions, Dr. William Schaffner, a professor of preventative medicine and infectious diseases at Vanderbilt University Medical Center, told the Times, is how frequent that human-to-human transmission is.

Ozzy Osbourne has revealed he's battling Parkinson's disease, opening up about his diagnosis in an emotional new interview.

The rock star spoke in an interview with Good Morning America that aired Tuesday, saying he was diagnosed with a form of Parkinson's disease after a fall last year.

"It's been terribly challenging for us all," Osbourne said, though his wife, Sharon Osbourne, described the diagnosis as "not a death sentence by any stretch of the imagination."

Osbourne previously postponed his planned 2019 tour dates, citing his health. "Words cannot express how frustrated, angry and depressed I am not to be able to tour right now," he said at the time. He reiterated to GMA that he "can't wait" to get back on the road again. "That's what's killing me," he said. "I need it, you know."

Now that he's revealed his diagnosis, Osbourne told GMA "I feel better," adding he hopes his fans "hang on and they're there for me because I need them." Osbourne, who's set to release a new album Ordinary Man next month, also promised, "I ain't going to go anywhere yet." Brendan Morrow

The just-starting Senate impeachment trial of President Trump has resurfaced reminders of what isn't allowed in the room where it happens: talking, electronics, questions from the press, among other things. And while it's true that coffee and other non-water drinks are always barred from the Senate floor, Sen. Rick Scott (R-Fla.) has just generously reminded us that another liquid will be available for slurping come trial time.

Yes, because one senator desperately needed a dose of dairy back in 1966, milk is allowed on the floor along with water. No senators have broken out the dairy this impeachment around, but keep an eye on Vermont Sens. Bernie Sanders (I) and Patrick Leahy (D), who've been spotted sipping milk together on special occasions for decades. Kathryn Krawczyk

Gallup revealed Tuesday that President Trump's approval rating during his third year in office set the record for the biggest partisan gap since the pollster began its records.

Republicans and Democrats are dramatically split — 89 percent of Republicans think Trump is doing a good job, compared to just 7 percent of Democrats. That 82-point difference is the largest ever, beating out the 79-point margin following Trump's second year in office. But what about the third subset, those pesky independents?

Trump's numbers don't crater among independents like they do with Democrats, and have improved over the last year — his 38 percent approval rating among non-affiliated respondents is higher than his 35 percent average rating to date, but they're still historically low. In the post-World War II era every other president has reached the 40 percent threshold among independents, with the lowest mark going to Jimmy Carter's 42 percent.

Overall, Trump checked in with a 42 percent approval rating during year no. 3, an uptick from his first and second years. It's not far behind the numbers averaged by former presidents like Barack Obama and Ronald Reagan at this point in their tenures, but it's still one of the lowest three-year averages during a first term since World War II. Only Carter's 37.4 percent trails. The poll was conducted over the phone from a random sample of 4,560 adults living in the U.S. by Gallup between Oct. 14, 2019 and Jan. 16, 2020. The margin of error is 2 percentage points. Read more at Gallup.

Prosecutors in Brazil have charged journalist Glenn Greenwald with cybercrimes, The New York Times reports.

The American journalist last year began publishing a series of stories at The Intercept that, as Columbia Journalism Review wrote, "sent shocks through Brazil" by appearing to show "that Sergio Moro, Brazil's justice minister and the former top judge in a major corruption investigation, colluded with federal prosecutors to convict prominent political figures." The Intercept said its reporting was based on "private chats, audio recordings, videos, photos, court proceedings, and other documentation" that was "provided to us by an anonymous source."

Brazilian prosecutors have now charged Greenwald "for his role in the spreading of cellphone messages that have embarrassed prosecutors," the Times reports. Prosecutors in a complaint claimed Greenwald is part of a "criminal organization" that hacked prosecutors' and other officials' cellphones.

The Intercept co-founder Jeremy Scahill on Twitter called these charges "despicable, dangerous and a crime against journalism," and others journalists quickly spoke out in Greenwald's defense.

"Regardless of your personal feelings about Glenn, this is a regime with deep authoritarian tendencies personally targeting a critical journalist," Vox's Dylan Matthews tweeted. "It's a horrendous abuse of power that everyone should denounce."

Greenwald in a statement to The Daily Beast said he "did nothing more than do my job as a journalist — ethically and within the law," calling the charges "an obvious attempt to attack a free press in retaliation for the revelations we reported about Minister Moro and the Bolsonaro government." He added, "We will not be intimidated by these tyrannical attempts to silence journalists. I am working right now on new reporting and will continue to do so." Brendan Morrow
