Algiers: A fire sparked by an electrical fault killed 18 African migrants and injured 43 others Tuesday at a camp in Algeria, emergency services and the Red Crescent said.

The blaze began before dawn at the camp housing about 600 migrants in Ouargla, 800 kilometres southeast of Algiers.

The victims’ nationalities were not immediately known.

“The fire broke out at 3am, killing 18 people and wounding 43,” Colonel Farouq Ashour said by telephone.

The president of the Algerian Red Crescent, Saida Bin Habiles, said the fire was sparked by a short circuit.

“A short circuit triggered the explosion of a heater and the fire,” Saida said.

She said that 27 people were still being treated in hospital.

The emergency services rushed to the scene to extinguish the fire.

The authorities have opened an investigation.

Since Libya descended into chaos in its 2011 uprising, Algeria has become a top North African destination for sub-Saharans seeking a better life.

Saida said that more than 4,000 migrants from Niger have been returned to their country by Algeria since 2014.

She said that 400 more migrants were due to be sent back to Niger from Ouargla, but it was not clear if any of them were from the camp hit by the blaze.

According to Saida, the migrants are free to come and go from the camp.

“They are constantly on the move. One day there could be 2,000 (migrants) and the next they are 200,” she said.

“We don’t lock up people as they do elsewhere.”
