The United Arab Emirates conveyed its sincere condolences and expressed its solidarity with the State of Kuwait over victims of fire in a building in the Mangaf area, which resulted in dozens of deaths and injuries.

In a statement, the Ministry of Foreign Affairs (MoFA) expressed its sincere condolences and sympathy with the government and people of Kuwait, and to the families of the victims, as well as its wishes for a speedy recovery for all the injured.

A fire in Kuwait killed 49 people, all Indian nationals, when it ripped through a building housing nearly 200 foreign workers on Wednesday, the government said.

The blaze, which broke out in the six-storey building south of Kuwait City at around dawn, also left dozens injured, the health ministry said.

Flames engulfed the lower floors as black smoke poured out of the upper-storey windows, unverified images posted on social media showed.

The interior ministry revised the death toll up to 49, from 35 issued earlier, after forensic teams scoured the charred building.
