power station

This huge hydroelectric power station, the largest in the world outside of China, supplies 90% of Paraguay's electricity needs, and 10% of Brazil's.

Videos verified by BBC Verify showed explosions and fires near a local power station late on Tuesday.

A spokesperson for RWE, the energy company which owns the facility, said the power station remained operational and the firm's priority was the safety of everyone on site.

And earlier this year, the government announced a deal with private investors to build the Sizewell C nuclear power station in Suffolk.

Of course, the picture of a Nigerien nuclear power station that Tsivilev has painted poses huge questions - technical, economic and in relation to security in a region notorious for Islamist militancy.
