The SpaceX space technology company is denying that debris from the explosion of one of its rockets has damaged the environment in Mexico.

Mexican environmental activists say detritus raining down from Elon Musk’s rocket company has caused die-offs of marine life. SpaceX said there were “no hazards to the surrounding area.”

SpaceX said on Thursday its debris recovery efforts after last week's Starship explosion have been hindered and it has sought cooperation from Mexico, whose president has raised the possibility of legal action against the company.
