PARIS (AP) — The French national rail company says high-speed lines have been hit arson attacks that heavily disrupted traffic on the day of the high-risk Olympics opening ceremony. Lines in the west, north and east of France were affected, the rail operator said. Government officials denounced the incidents hours before the opening ceremony of the Paris Olympics, which are happening around France, though there was no immediate sign of a link to the Games. Prosecutors opened an investigation, saying that the crimes could carry a 20-year sentence and fines of hundreds of thousands of euros.

ATLANTA (AP) — Former President Barack Obama and former first lady Michelle Obama have endorsed Kamala Harris in her White House bid, giving the vice president the expected but still crucial backing of the nation’s two most popular Democrats. The endorsement was announced Friday in a video showing Harris accepting a joint phone call from the former first couple. It comes as Harris builds momentum as the party’s likely nominee after President Joe Biden’s decision to end his reelection bid and endorse her against Republican nominee and former President Donald Trump. Harris thanks the Obamas for their backing and says she looks forward to campaigning with them ahead of the Nov. 5 Election Day.

DALLAS (AP) — Southwest Airlines plans to drop the open-boarding system it has used for more than 50 years and will start assigning passengers to seats, just like all the other big airlines. The airline said Thursday that preferences have changed over the years and the vast majority of travelers now want to know where they are sitting before they get to the airport. Southwest’s unusual boarding process started as a fast way to load passengers and limit the time that planes and crews spend sitting idly on the ground, not making money. It helped the airline squeeze a few more flights into the daily schedule. Southwest also plans to offer redeye flights for the first time.
