Facebook has taken down hundreds of accounts and pages after tracing them back to Russia's news agency.

The social media website said Thursday that it had removed 364 pages that were being run by a network originating in Russia and whose creators were engaging in "coordinated inauthentic behavior." Facebook says the pages, some of which were meant to look like independent news sources, were linked to employees of Sputnik, the news agency owned by the Russian government, who used fake accounts to misrepresent themselves.

"Some of the Pages frequently posted about topics like anti-NATO sentiment, protest movements, and anti-corruption," Facebook says. Nearly 800,000 people followed these removed pages, which also spent more than $100,000 in advertising.

Additionally, Facebook says it uncovered a separate network of Ukrainian pages and accounts that also originated in Russia, with 26 pages being removed that were bolstered by fake accounts. "We are constantly working to detect and stop this type of activity because we don't want our services to be used to manipulate people," Facebook said. Brendan Morrow

"The Fake News is saying that I am willing to meet with Iran, 'No Conditions,'" President Trump tweeted Sunday night. "That is an incorrect statement (as usual!)." Where would the news media get such an idea?

Here, for example, are Secretary of State Mike Pompeo and Treasury Secretary Steven Mnuchin saying Trump is willing to meet with Iran with no preconditions just last week.

Well, maybe Pompeo and Mnuchin just misunderstood Trump? Here's Trump in June.

And last year:

Assuming there isn't some esoteric difference between "no conditions" and "no preconditions," it appears that the "incorrect statement" came from the president himself. Add any parenthetical accentuation you see fit. Peter Weber

Talks between Venezuelan President Nicolás Maduro's government and the country's opposition party are officially done, six weeks after Maduro's representatives stopped attending the discussions.

Opposition leader Juan Guaidó made the announcement on Sunday. The talks, mediated by Norway and held in Barbados, were called as a way to try to end the escalating political crisis engulfing Venezuela. Millions of people have left the country, due to poverty, inflation, and food and medicine shortages. Guaidó, the leader of Venezuela's National Assembly, said Maduro was not fairly elected in 2018, and he is the legitimate president, an assertion backed by the United States and dozens of other countries.

The opposition tried to launch a military uprising in the spring, but it failed, and Maduro has retained power, refusing to step down. In August, his representatives left the talks, citing President Trump's new sanctions against the country. When talks were still taking place, the opposition called for a new, free election, but Maduro's representatives would not even broach the subject, Reuters reports. Catherine Garcia

Purdue Pharma, the drugmaker accused of playing a major role in the opioid epidemic, filed for Chapter 11 bankruptcy protection in New York on Sunday. The move was expected after the company and its owners, the Sackler family, reached a tentative settlement with 24 states and thousands of local governments last week. Under the settlement, the Sacklers would wash their hands of Purdue, putting up $3 billion of the family's estimated $13 billion fortune and turning Purdue into a trust, with profits from OxyContin and other drugs going to the plaintiffs.

This isn't the end of the road for Purdue yet, though, as The Associated Press explains.

The thousands of plaintiffs who have not yet signed on to the settlement, including about half of U.S. states, will likely object to the settlement in bankruptcy court, and there are open questions about whether the proposed settlement is really worth $12 billion and how the money would be distributed. Purdue and the lawyers representing the parties that agreed to the settlement argue that nobody is served by long, costly litigation.

Recent court filings suggest much of the Sackler wealth has been stashed offshore since 2008, making it likely out of reach of U.S. plaintiffs, especially if the company dissolves without admitting wrongdoing or being found guilty in court. "The Sacklers are going to be left with plenty of money after this,'' Adam J. Levitin, a bankruptcy expert at Georgetown Law, tells The Washington Post. "There is a desire that the Sacklers pay some blood money, but it's never going to be enough to make everyone happy.''

OxyContin accounts for only a slice of the opioid drugs sold in the U.S., but Purdue's aggressive and misleading marketing is blamed for helping spark the opioid addiction crisis. Since 1999, more than 200,000 people have died from overdoses of prescription opioids. Peter Weber

No deal was reached on Sunday between the United Auto Workers and General Motors, resulting in about 49,000 union members going on strike at midnight Monday.

This is the first national UAW strike since 2007, and was authorized Sunday morning in Detroit during a UAW meeting of regional leaders. The UAW said it is asking for more affordable health care, fair wages, and profit sharing, and could not reach an agreement with GM. "We stood up for General Motors when they needed us most," UAW Vice President Terry Dittes said in a statement. "Now we are standing together in unity and solidarity for our members, their families, and the communities where we work and live."

GM said it offered better health benefits and to create more than 5,400 new jobs, adding, "We have negotiated in good faith and with a sense of urgency. Our goal remains to build a strong future for our employees and our business." Contract talks will start back up again Monday morning, UAW spokesman Brian Rothenberg said. Catherine Garcia

In his new memoir, former British Prime Minister David Cameron says he believes current Prime Minister Boris Johnson only backed Brexit because "it would help his political career."

Cameron is candid when it comes to sharing his feelings about Johnson and Michael Gove, a fellow Conservative Party member who served in Cameron's cabinet and is now chancellor to the Duchy of Lancaster. U.K.'s Sunday Times published an excerpt of the memoir, in which Cameron calls the men "ambassadors for the expert-trashing, truth-twisting age of populism" and accuses Gove of being disloyal to both him and Johnson.

Because the Conservative Party's manifesto committed to holding a referendum on the U.K.'s membership in the European Union, Cameron called for a vote in 2016. The Leave campaign won, with 52 percent of the vote compared to Remain's 48 percent. Cameron was in favor of remaining, and he says Johnson merely took the "lead on the Brexit side — so loaded with images of patriotism, independence, and romance — [so he] would become the darling of the party." Johnson, he continued, "risked an outcome he didn't believe in because it would help his political career."

Cameron, who resigned as prime minister shortly after the vote, told the Times on Saturday that he understands "some people will never forgive me" for calling the referendum. Liberal Democrat leader Jo Swinson is one of those people, saying Cameron "put the interests of the Conservative Party ahead of the national interest." Catherine Garcia

President Trump had some pretty belligerent language Sunday about the perpetrators of an attack Saturday on Saudi Arabia's state oil company, Saudi Aramco, saying the U.S. is "locked and loaded depending on verification" of the "culprit," but "are waiting to hear from the Kingdom as to who they believe was the cause of this attack, and under what terms we would proceed!" Trump didn't identify the suspected culprit, but Secretary of State Mike Pompeo pointed the finger at Iran. Iran denies any involvement, and Yemen's Houthi rebels, frequently bombed by the Saudis, claimed responsibility.

The idea that the U.S. should attack another country, presumably Iran, if Saudi Arabia thinks that's what should be done, because the Saudi oil supply was disrupted, didn't sit well with everyone, including — but not only — Democrats.

But Trump would likely have disapproved, too, a few years ago.

Things have been tense in the region for months, with oil tankers attacked or seized as the U.S. seeks to strangle Iran's oil exports. "Because of the tension and sensitive situation, our region is like a powder keg," warned Iranian Brig. Gen. Amir Ali Hajizadeh. "When these contacts come too close, when forces come into contact with one another, it is possible a conflict happens because of a misunderstanding." Peter Weber
