Commemoration ceremonies to be held around the world for the nearly 3,000 killed in 2001 terror attack on US. Plus, JD Vance sets out his stall as heir to Donald Trump

Good morning. It is a sombre day for the nation as people gather to mourn and remember the nearly 3,000 victims of the attacks on September 11 2001, when 19 al-Qaida hijackers seized control of four airliners, slamming two of the planes into the World Trade Center, one into the Pentagon in Arlington, Virginia, and the fourth into a field in western Pennsylvania.

We have comprehensive coverage of the anniversary, which will be marked by ceremonies around the world. There are stories of the day from people who were there.

With his approval rating at a historic low, Trump brought down the curtain on the Republicans’ first ever midterm convention by pleading with supporters to do him “the biggest favor” and “pretend” they are voting for him in November’s US elections.

JD Vance, meanwhile, made a clear pitch that he should be the heir to Trump with a blistering speech that featured exaggerated claims of success, criticism of the Democrats as “lunatics” and an aggressive dismissal of a protester waving a Mexican flag.

A US appeals court has rejected Trump’s attempt to impose sweeping restrictions on mail-in voting before November’s high-stakes midterm elections, dealing a fresh blow to the president’s attempted crackdown.

California has adopted what Gavin Newsom described as “nation-leading” legislation that bans addictive social media features for young users, regulates companion chatbots and implements new safeguards around AI.
