Rules:

Rule 1: posts have the following requirements:
- Post news articles only
- Video links are NOT articles and will be removed.
- Title must match the article headline
- Not United States Internal News
- Recent (Past 30 Days)
- Screenshots/links to other social media sites (Twitter/X/Facebook/Youtube/reddit, etc.) are explicitly forbidden, as are link shorteners.
Rule 2: Do not copy the entire article into your post. The key points in 1-2 paragraphs is allowed (even encouraged!), but large segments of articles posted in the body will result in the post being removed. If you have to stop and think "Is this fair use?", it probably isn't. Archive links, especially the ones created on link submission, are absolutely allowed but those that avoid paywalls are not.
Rule 3: Opinions articles, or Articles based on misinformation/propaganda may be removed. Sources that have a Low or Very Low factual reporting rating or MBFC Credibility Rating may be removed.
Rule 4: Posts or comments that are homophobic, transphobic, racist, sexist, anti-religious, or ableist will be removed. “Ironic” prejudice is just prejudiced.
Posts and comments must abide by the lemmy.world terms of service UPDATED AS OF 10/19
Rule 5: Keep it civil. It's OK to say the subject of an article is behaving like a (pejorative, pejorative). It's NOT OK to say another USER is (pejorative). Strong language is fine, just not directed at other members. Engage in good-faith and with respect! This includes accusing another user of being a bot or paid actor. Trolling is uncivil and is grounds for removal and/or a community ban.
Rule 6: Memes, spam, other low effort posting, reposts, misinformation, advocating violence, off-topic, trolling, offensive, regarding the moderators or meta in content may be removed at any time.
Rule 7: We didn't USED to need a rule about how many posts one could make in a day, then someone posted NINETEEN articles in a single day. Not comments, FULL ARTICLES. If you're posting more than say, 10 or so, consider going outside and touching grass. We reserve the right to limit over-posting so a single user does not dominate the front page.

We ask that the users report any comment or post that violate the rules, to use critical thinking when reading, posting or commenting. Users that post off-topic spam, advocate violence, have multiple comments or posts removed, weaponize reports or violate the code of conduct will be banned.

All posts and comments will be reviewed on a case-by-case basis. This means that some content that violates the rules may be allowed, while other content that does not violate the rules may be removed. The moderators retain the right to remove any content and ban users.

Ukraine blows up main railway connection between Russia and China (www.politico.eu)

Ukraine’s security service blew up a railway connection linking Russia to China, in a clandestine strike carried out deep into enemy territory, with pro-Kremlin media reporting that investigators have opened a criminal case into a “terrorist attack.”

The SBU set off several explosions inside the Severomuysky tunnel of the Baikal-Amur highway in Buryatia, located some 6,000 kilometers east of Ukraine, a senior Ukrainian official with direct knowledge of the operation told POLITICO.

“This is the only serious railway connection between the Russian Federation and China. And currently, this route, which Russia uses, including for military supplies, is paralyzed,” the official said.

Four explosive devices went off while a cargo train was moving inside the tunnel. “Now the (Russian) Federal Security Service is working on the spot, the railway workers are unsuccessfully trying to minimize the consequences of the SBU special operation,” the Ukrainian official added.

Ukraine’s security service has not publicly confirmed the attack. Russia has also so far not confirmed the sabotage.

I haven't heard of anything to refute that, and have heard things to confirm that.

If you have any info you'd like to submit, please do so.

Edit: By refute that, I mean refuting that the jet fuel burning caused the metal to weaken onto collapse.

Well, here's what 5 minutes of research yielded

For example, according to www.911research.wtc7.net, steel melts at a temperature of 2,777 degrees Fahrenheit, but jet fuel burns at only 1,517 degrees F. No melted steel, no collapsed towers.

https://www.scientificamerican.com/article/fahrenheit-2777/

All materials weaken with increasing temperature and steel is no exception. Strength loss for steel is generally accepted to begin at about 300°C and increases rapidly after 400°C. By 550°C steel retains approximately 60% of its room temperature yield strength, and 45% of its stiffness.

https://www.steelconstruction.info/Fire_damage_assessment_of_hot_rolled_structural_steelwork#:~:text=All%20materials%20weaken%20with%20increasing,and%2045%25%20of%20its%20stiffness.

Jet fuel burns at 1500f, which is 815c. At 800c steel retains less than 20% of the strength that it has at room temperature. There you go, fully debunked with minimal effort and extremely basic facts.

The problem is, I read contradictory information, so both sides say they're correct..

For example, this...

FACT: Jet fuel burns at 800 to 1500 degrees Fahrenheit, not hot enough to melt steel (2750 degrees Fahrenheit). However, experts agree that for the towers to collapse, their steel frames didn’t need to melt, they just had to lose some of their structural strength—and that required exposure to much less heat.

That doesn't look like contradictory information to me.

[–] [email protected] -1 points 9 months ago* (last edited 9 months ago)

I meant contradictory to the origional comment I was replying to, that was talking about alt reasons for the tragedy. Replied to the wrong comment.
