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

Just when she thought she was out...

Chrissy Teigen returned to Twitter on Friday weeks after generating headlines for deleting her account, as the exit apparently wasn't all she expected it might be.

"Turns out it feels TERRIBLE to silence yourself and also no longer enjoy belly chuckles randomly throughout the day and also lose like 2000 friends at once," she wrote.

Teigen, who had nearly 14 million followers when she deleted her Twitter account in March, had previously explained she was leaving because the platform "no longer serves me as positively as it serves me negatively." She clarified this was "absolutely NOT Twitter's fault" and also wasn't the result of being bullied by trolls, but she said she was struggling to "come to terms with the fact some people aren't gonna like me."

Less than a month later, Teigen's account was back online on Friday, and she's apparently got a lot of catching up to do, joking she's spent "weeks just saying tweets to shampoo bottles." Teigen added that in returning to Twitter, she's choosing to "take the bad with the good," which fans can perhaps see as a more positive lesson out of this whole saga than the idea that there's truly no escape from Twitter for anyone.

One of the Louisville police officers who shot Breonna Taylor is writing a book, but Simon & Schuster is now backing away from plans to be involved.

The publisher announced it has "decided not be involved in the distribution of" a book written by Sgt. Jonathan Mattingly, one of the officers involved in the raid that Breonna Taylor was killed in last year, The New York Times and CNN report.

Officers in March 2020 were executing a no-knock warrant at Taylor's apartment in Louisville, Kentucky, and Mattingly was shot by Taylor's boyfriend, who says he thought they were intruders and was firing a warning shot. Taylor was killed after the officers returned fire. According to the Times, Mattingly "fired at least one of the six shots that hit Ms. Taylor, but not the lethal bullet."

It had previously been reported by the Louisville Courier Journal that Post Hill Press would publish Mattingly's book, The Fight for Truth: The Inside Story Behind the Breonna Taylor Tragedy. But after facing criticism, Simon & Schuster said it only "learned of plans by distribution client Post Hill Press to publish a book by Jonathan Mattingly" on Thursday as this report emerged and will no longer be involved.

Prior to Simon & Schuster's announcement, a spokesperson for Post Hill Press told the Times it was standing by its decision to publish the book, as "in the case of Sergeant Mattingly, the mainstream media narrative has been entirely one-sided related to this story and we feel that he deserves to have his account of the tragic events heard publicly." Mattingly previously sued Taylor's boyfriend for assault and battery last year. Brendan Morrow

You may soon need a license to drive and vote in Texas but not carry a handgun in public.

After years of failed attempts by gun advocates, the Texas House on Thursday gave initial approval to a bill that would drop the state's requirement that most handgun owners obtain a $40 license to carry their firearm in public, concealed or openly. Currently, Texans 21 and over with no criminal record can get a license to carry a handgun if they complete a training requirement, don't have a drug addiction, and can "exercise sound judgment with respect the proper use and storage of a handgun," the Austin American-Statesman explains.

The measure would drop the license requirement, though federal background checks would remain in place for most handgun purchases, with exceptions for private and gun show sales. It passed 84-56, mainly along party lines; five Democrats voted in favor, one Republican voted against. The legislation needs another vote in the House, and it faces an uncertain future in the state Senate.

The El Paso delegation led the unsuccessful opposition to the bill, HR 1927. After a gunman murdered 23 people at a Walmart in 2019, followed weeks later by the mass shooting of seven people in Midland Odessa, "there were roundtable discussions and stakeholder meetings and a lot of promises — and I was hopeful, members, even knowing the political realities, I was hopeful," said state Rep. Joe Moody (D). "I'm so tired of doing nothing," he added. "I'm so tired of catering to a very small number of very loud people whose thinking about guns is wrapped up in unfounded fears and bizarre conspiracy theories."

Permitless carry has the support of the Texas Republican Party and the National Rifle Association. It is opposed by law enforcement groups, firearms trainers, and groups of clergy and veterans. At a break in the five-hour debate, a group of gun control advocates prayed and sang "Amazing Grace" in the gallery, before being escorted out by law enforcement. Peter Weber

One in five Americans still say they won't get the COVID-19 vaccine, despite the willingness by Americans to put all manner of junk in their bodies and eagerness to take anything offered freely, Jimmy Kimmel sighed on Thursday's Kimmel Live. Dr. Anthony Fauci "must be beating his head against the wall. Dr. Fauci appeared today before a congressional subcommittee on COVID-19 and was forced to endure the relentless stupidity of a shaved ape from Ohio named Jim Jordan," who screamed that Americans' liberties have been assaulted by public health measures. "Yeah, you know who else was assaulted? Those wrestlers when you were their coach at Ohio State," Kimmel said. "I guess that you didn't notice."

"Meanwhile, there are new details in the sordid saga of future former Florida congressman Matt Gaetz," Kimmel said. "Yesterday we learned that Gaetz was involved in more wild house parties than Kid 'n Play in the '90s. Reportedly, there were drugs and sex at these parties, where women were given gifts and money in exchange for their 'participation,' much of it paid through Venmo."

Accused ringleader Joel Greenberg made at least 150 payments to young women, including at least 16 to a future Gaetz girlfriend, Kimmel said, "and of course we know about all of this because stupid Joel Greenberg made his Venmo transactions public, as did Matt Gaetz — they didn't check the privacy box. What's the opposite of a criminal mastermind? "

"Gaetz faces an intensifying investigation in which authorities seized his phone last winter," Seth Meyers said at Late Night, and "I'm no lawyer, but it can't be good when they seize your phone. No one's happy to have their phone seized," even if it's just your wife, he joked. "Chances are pretty high that if you've broken the law, there's evidence of it on your phone, especially since Gaetz was reportedly using Cash App and Venmo to make payments to his indicted buddy."

We're also learning more about those parties Gaetz, Greenberg, and their GOP friends would allegedly hold, Meyers said. "You know, my grandmother used to say nothing good ever happens after midnight, and I'd say the same is true about anything that happens at a party in a gated community in suburban Orlando where they make you give up your phone."

Joel Greenberg, 36, and Rep. Matt Gaetz (R-Fla.), 38, became friends soon after Greenberg was elected Seminole County tax collector and Gaetz won a seat in Congress in 2016. Both men were "brash politicians who hailed from families of considerable wealth and who themselves rose to power quickly," and "they also enjoyed parties and the company of women," The Washington Post reports, citing people who know both Gaetz and Greenberg. That latter interest — woman and parties — is also why both men are under federal investigation.

Before the feds got involved in late 2019 or early 2020, Greenberg had already been on the radar of local law enforcement — for, among other things, allegedly misusing public funds, handing lucrative and unnecessary contracts and state jobs to friends and allies, and impersonating a police officer, pulling over a woman for speeding using a badge and lights on his private vehicle.

But local police did not start investigating Greenberg until, according the a federal indictment, he tried to derail a GOP primary challenger, prep school music teacher Brian Beute, by sending his school a fraudulent note claiming Beute had carried on an inappropriate sexual relationship with a student. Beute roped in a lawyer acquaintance, David Bear, who convinced the sheriff's office that whoever was behind the smear campaign had committed a crime. Bear also successfully encouraged the sheriff's office to seek help from the feds, the Post reports.

"When authorities arrested Greenberg and sifted through his electronic records and devices — according to documents and people involved in the case — they discovered a medley of other alleged wrongdoing, leading them to open an investigation of possible sex trafficking involving a far more high-profile Florida Republican," Gaetz, the Post reports. Beute thought about dropping the matter after local investigators cleared him of having sex with a student, but "he decided not to," Bear told the Post. "All of these other things mushroomed out of that one decision for him to stand tall."

Greenberg, facing 33 counts including sex trafficking of a child, is reportedly cooperating with prosecutors to earn some leniency. Gaetz denies the alleged focus of his investigation — paying for sex and having sex with a minor across state lines — and has not been charged or formally accused of wrongdoing.

Indianapolis police said early Friday that eight people have been confirmed dead after a mass shooting at a FedEx facility on the grounds of the Indianapolis International Airport late Thursday. Along with the eight people shot dead, at least four people have been hospitalized, one of them with critical injuries, Indianapolis Metropolitan Police Department spokeswoman Genae Cook told reporters. Two other people were treated at the scene. Police said the gunman shot and killed himself after officers arrived at the FedEx facility just after 11 p.m. Thursday night.

"We are aware of the tragic shooting at our FedEx Ground facility near the Indianapolis airport," FedEx said in a statement early Friday. "Safety is our top priority, and our thoughts are with all those who are affected. We are working to gather more information and are cooperating with investigating authorities." Peter Weber
