In Brazil, Twitter is testing tweets that disappear after 24 hours, AP reports.

The state of play: The company says the ephemeral tweets — "fleets" — are designed to allay the concerns of new users who might be turned off by the public and permanent nature of normal tweets.

How it works: Fleets can't be retweeted and don't have "likes."

  • People can respond to them, but the replies show up as direct messages to the original tweeter, not as a public response.

The feature is reminiscent of Snapchat snaps.

  • Twitter said it may bring fleets to other countries depending on how the Brazil test goes.

Hiroshima mayor warns of rise of nationalism on 75th anniversary

Hiroshima's Mayor Kazumi Matsui on Thursday urged the international community to work together to defeat the coronavirus pandemic and warned against an increase in "self-centered nationalism," per the Washington Post.

Why it matters: He said at a remembrance service on the atomic bombing of the Japanese city that the 1918 flu pandemic killed millions as countries fighting in World War I were unable to overcome the threat together, per DPR. "A subsequent upsurge in nationalism led to World War II," he added. The U.S. bombing of Hiroshima on Aug. 6, 1945 and Nagasaki three days later contributed to the end of World War II, but tens of thousands of people died. At the service, Prime Minister Shinzo Abe lamented nuclear weapons' "inhumanity," but he didn't mention Japan's wartime past, WashPost noted.

LeBron James responded on Wednesday night to President Trump's comments calling NBA players "disgraceful" for kneeling during the national anthem to protest racism and that he won't watch games because of the action.

The big picture: Trump has repeatedly criticized sports players for taking the knee since 2016. But James said during a news conference, "I really don’t think the basketball community are sad about losing his viewership, him viewing the game." November's elections marked "a big moment for us as Americans," he said. "If we continue to talk about, 'We want better, we want change,' we have an opportunity to do that," he added. NBA Commissioner Adam Silver has said the league will "respect peaceful protest."
