Two trains operated by Russian aluminium giant Rusal collided in Guinea's capital Conakry on Monday, killing at least one person and injuring several others, witnesses said and footage on social media showed.
The world's third-largest aluminium producer operates three bauxite mines and an alumina refinery in the coastal West African nation. The Guinea mines currently account for 42% of Rusal's total bauxite capacity.
Rusal did not immediately reply to a request for comment.
"It was a moving train that collided with another that had broken down and was parked," Lamine Camara, a resident of the neighbourhood where the accident took place on the outskirts of the capital, told Reuters.
Another witness gave a similar account.
Images shared on social media showed multiple derailed train cars piled on top of each other and thick, grey smoke. Firefighters dug through the mangled wreckage while paramedics carried a body covered with a white sheet into an ambulance.
The Russian firm has been a strong presence in Guinea since the Soviet era. It has said it will maintain its operations there despite a military coup on Sept. 5 that overthrew longtime president Alpha Conde.
