In Burkina Faso, rescue workers have found no survivors in a rescue chamber deep inside a flooded zinc mine. 

The Perkoa mine, owned by Canadian firm Trevali Mining Corp and located about 120km (75 miles) west of the capital Ouagadougou, was abruptly submerged on April 16 after torrential rain fell unexpectedly during the country’s dry season.
