A fire that broke out in a building housing workers in the city of Mangaf in southern Kuwait early on Wednesday has killed at least 41 people, the country's deputy prime minister Sheikh Fahad Yusuf Saud Al-Sabah said during a visit to the site.

The deputy PM accused real estate owners of violations and greed, saying those factors contributed towards the incident.

"Unfortunately, the greed of real estate owners is what leads to these matters," said Sheikh Fahad, who also runs the interior and defense ministries.
