More than 200 people were killed in a massive fire on Sunday that forced residents to flee their homes, leaving behind tens of thousands of dollars in damaged property.

The fire, at a refinery in the city of Al-Ras, is one of the deadliest fires in Kuwait since 2005.

The Associated Press reported that at least 25 people were taken to hospitals after the blaze.

The Kuwaiti health ministry said a total of 1,400 people were displaced from their homes.

“This is a humanitarian tragedy,” Kuwaiti Prime Minister Khalid al-Jabouri told reporters, adding that more than 3,500 people have been treated at the hospitals, including 2,200 children.

“We will not give up our fight,” he said.

The fires in Al-Qaaimiya, a small town in Kuwait’s north, were reported to have started around 6 a.m. local time, according to Al Jazeera.

An official with the state-run news agency, al-Hayat, said the blaze started in a building used as a processing facility for the chemical giant, and that the fire was contained within two hours.

The city’s governor said the city is still under curfew and has been closed for a period of time.

The United States has been sending a military plane to the Gulf region to help with the cleanup efforts.

Kuwaiti officials have also ordered the evacuation of more than 2,000 people from the city to other areas of the country.

The death toll in Kuwait has risen to more than 600.

The U.S. State Department said it was sending food, medical supplies, fuel, and emergency personnel to the country to help rebuild the affected region.
