Elon Musk has fired Omead Afshar, the head of Tesla’s sales and manufacturing operations in North America and Europe, multiple outlets reported Thursday. The apparent expulsion of the top exec comes as the billionaire’s car company flounders under plummeting sales in both the U.S. and the EU.

Omead Afshar, a long-time Musk lieutenant, was tasked with improving the company’s business in North America and Europe late last year but sales continue to drop in both.
