Thirteen Pakistanis, including eight children, died when a fire swept through their makeshift dwellings in a farming estate in the Jordan Valley, Jordan’s civil defense said.

There were three other injuries in the fire that broke out after midnight that initial signs showed could have been an electrical fire, civil defense spokesman Iyad al Amre said in a statement.

Thousands of foreign laborers live in wretched conditions in private farms in the Jordan Valley, a fertile vegetable and fruit growing area.
