Tech billionaire Elon Musk is hosting a live-streamed chat on his social media platform X on Thursday with a leader of Germany's far-right party, amplifying its message ahead of an upcoming national election and raising concerns across Europe about potential meddling by the world's richest man.

A Thai court on Wednesday issued an arrest warrant for an alleged hit man who shot dead a former Cambodian opposition lawmaker in a brazen attack in Bangkok's crowded old quarter, police said.

Musk is using his influential social media platform X to endorse the far right in Germany ahead of its Feb. 23 election.

Musk has written a number of recent social media posts to show his support of far-right populists in Europe and to attack politicians on the left. Now, European leaders believe, is the time to brush him back.
