The European Commission has sent a formal notice to Elon Musk’s X requesting information on the social media platform’s provisions to deal with illegal content, disinformation and abusive material posted on the site in the wake of the Israel-Hamas conflict.

European Commissioner for the Internal Market Thierry Breton, who announced the move on his X account on Thursday, said it marked the first step in an investigation to determine X’s compliance with the European Union‘s Digital Services Act (DSA).

“The DSA is here to protect both freedom of expression & our democracies — including in times of crisis,” wrote Breton.
