BRUSSELS EU industry chief Thierry Breton on Tuesday warned Elon Musk of disinformation spread on his X messaging platform following Palestinian Islamist group Hamas' surprise attack on Israel.

"I therefore invite you to urgently ensure that your systems are effective, and report on the crisis measures taken to my team," Breton told Musk in a letter dated Oct. 10 and seen by Reuters.
